The MIT Swapfest, also known as "Flea@MIT" is a great event. I lived in Boston
for four years, until last month when I moved, but I went to the swapfest many
times and always found interesting things. There is a small-ish outdoors area
and a huge indoors area. There are even people selling snacks (usually
doughnuts and barbeque food, coffee and Coke) by one of the entrances. LOL,
just don't do what I did the first time, and think the small outdoors part was
the whole thing!
