My main priority is improving the Florida page and the destinations within it, particularly in the South Florida area. I was able to get the Florida Gold Coast page up to usable, and I'm pretty satisfied with it for now, so I'm focusing on improving the Miami and Miami Beach pages, which are currently of very poor quality.
Maintaining the high-quality Washington, D.C. pages, bringing "guide" districts up to "star"
Other general tasks, like adding templates to stubs
Way to spend a day alone in a new city. I always make time to just wander around and see what neighborhoods I come across. Growing up, I always traveled with my mom, who was a horrible planner. Thanks to her, we always discovered great little neighborhoods and sights we might not have come across.
Museum. The Smithsonian American History museum in DC.
Pet peeve. "Hop on, hop off" tours. I would rather spend a couple of hours in one good museum, or just walking around on my own, then sitting on a bus trying to see everything.
