Finally warming up around here (though we did get hit by the [largest 24-hour temperature drop in recorded history][1] while we were up visiting my folks). We took the kids to a [Holi][2] celebration, which was a huge mess and a ton of fun. The colors don't come through here but I think the joy does.

|

Then we drove up to DC, left the kids with my folks, and took the train to Baltimore to catch [my friend's][3] show and spend a little bit of time in the city. We stayed at the [Pendry][4] which was super nice -- we'll be back. Sold the old car while were up there -- 🪦 legend.

I did my yearly trip to Vegas to watch basketball with some old friends. Great times. We had dinner one night at [Mott 32][5] at the Venetian, and I'm not really a fine dining guy but this was killer.

Claire went to visit a friend out in California, and I picked up a [double trailer][6] off CraigsList so I could take both kids around on the bike. We passed a couple as we were riding downtown and Nev yelled, "Look at us! We’re the luckiest kids in the world!" which I'm writing down here to remember forever.

April's looking much calmer. I've got [a race][7] in a few weeks, feeling pretty good about that. I'd like to get to where I'm doing 3-4 big races a year; I struggle to get up off the couch without some kind of deadline. Otherwise, prepping that hackathon project I [mentioned last month][8] for our big reveal in early May, biking around town, and [Gridfinity][9]-ing my entire house.

> That's not why brand age watches look strange. Brand age watches look strange because they have no practical function. Their function is to express brand, and while that is certainly a constraint, it's not the clean kind of constraint that generates good things. The constraints imposed by brand ultimately depend on some of the worst features of human psychology. So when you have a world defined only by brand, it's going to be a weird, bad world.

> None of that happens if the internet exists. Instead of fleeing to Seattle in search of a purpose in life, Kurt Cobain would’ve joined a subreddit that made living in Aberdeen three percent more bearable, he would have expressed his jadedness with society on Thought Catalog, and he would have uploaded rough demos to his SoundCloud as his attempt at making it in the biz. He wouldn’t have met any of the people who either inspired his music or directly made it with him. More important, the Seattle scene itself never would have materialized. The internet disincentivizes people young and old from going out into the world, from making necessary human connections, and from forging a collective artistic voice together. That’s why there’s never gonna be another Cobain.

|
||||
|
||||
Earlier this week, the District broke local temperature records for one of the
|
||||
warmest March 10ths measured in decades, but within 24 hours, D.C. temperatures
|
||||
crashed to the point where parts of the D.C. area experienced freezing rain and
|
||||
snow!
|
||||
|
||||
While the drop in temperature was forecasted, it truly felt impossible while
|
||||
the sun was shining and the warm air truly felt like spring.

|

In other words, this year’s ‘[22]false spring‘ hit Washingtonians harder than
|
||||
it ever has, and quickly humbled our hopes for an end to the cold winter
|
||||
weather.

|
||||
How much did the temperature drop around D.C. in 24 hours?
|
||||
|
||||
The District experienced a 51-degree swing, from 84 degrees and sunny one day,
|
||||
to 33 degrees with freezing rain and snow the next!
|
||||
|
||||
The remarkable drop in temperature is the largest ever recorded within 24 hours
|
||||
in Washington, D.C., with records dating back to 1929.
|
||||
|
||||
The only ever similar temperature drop on record in D.C. was nearly a century
|
||||
ago, in 1934, when temperatures went from 65 degrees to 14 degrees in a single
|
||||
day.

|
||||
|
||||
Did the record-breaking temperature ruin any of the District’s blooms or
|
||||
blossoms?
|
||||
|
||||
Washington, D.C., is home to many gorgeous and iconic blooms that bring the
|
||||
city to life every spring, but not all of them bloom at the same time, which
|
||||
means that one bad storm is highly unlikely to impact all of the blooms and
|
||||
blossoms around the District.
|
||||
|
||||
That being said, two particular blooms were at the highest risk of impact from
|
||||
the historic temperature drop and subsequent weather:
|
||||
|
||||
• The Okame cherry blossoms were just about at their peak bloom before the
|
||||
temperature shift, which means that most of their flowers likely fell due
|
||||
to shock from the weather.
|
||||
• The magnolia trees around the District, which were just about to start
|
||||
flowering, seemingly made it through the day unscathed. [23]According to
|
||||
the Smithsonian Garden, the magnolia trees around the Enid A. Haupt Garden
|
||||
and the Smithsonian Castle seemed to be progressing towards their bloom as
|
||||
if unfazed.
|
||||
|
||||
Fortunately, the District’s iconic Yoshino cherry blossoms were not impacted by
|
||||
the major shift as they are not expected to bloom until the very end of the
|
||||
month or the start of April.
