I hear you on the hurricane issue. I'm in the habit of buying trip insurance anytime I visit anyplace remotely coastal.
Right now am bugging the hubster to see if he wants to come visit his sister in Hoboken...if not I may just do a quick Saturday/Sunday trip. I've visited NY many times and am no stranger to attending shows alone when it's someone I really want to see, so no big. I realize I need to not dink around much longer on getting a ticket, hotel room, etc., tho.
Used to live in D.C. myself. Was just telling the hub that in some ways I miss it...the annual Fugazi show...seeing everyone for cheap at the Black Cat...the old 9:30 Club...not that we hurt for live music in these parts, but we sometimes don't get the big 'name' acts the East Coast sees.
