I love this time of year in DC-- the cherry trees are blooming and the summer heat and humidity haven't  kicked up yet: 

There are a few hazards, though.  A few days ago, a thunderstorm swept through the area, with residents waking up to a light drizzle and a heavy, gray sky.  At around 7AM, there was an almighty crash and bright flash, virtually knocking anyone who was still in bed onto the floor.  A few minutes later, some more thunder and lightning but not nearly so sharp.  I stuck my head out the window and looked up and down the street but nothing seemed amiss.  Turns out a tree a block and a half away was struck by lightning.  I guess that's how the DC height restrictions are enforced!
