The All Star Sports, and the Cont. at least it is a good way to see the pins that are out there, and meet some other newbies..most traders will be happy to at least show you their pins, even if you can't trade, that way you can decide what ones you would like to go for,
There are also some traders, that put other pins on their lanyards, the CM lanyard pins for example, and trade 1 for 1..I in doubt, look for us at the Contempory most fri nights, there are usually 4 or 6 of us together, and are always glad to help..I wear my green Disboards pin on my lanyard, Bob wears a villian lanyard, and My DH usually wears a teaser lanyard w/ a lot of good pins Wet Paint etc. just to show people what they look like, I have short blonde/white hair..usually you can't miss me unfortunately, I can't get away w/ anything..LOL
You can try Boardwalk, but the last people I talked too said there weren't many there the last time they went.. but it doesn't hurt to drop over..
