Ah, a Bowdoin student. Nice campus.
Amiga Crossing was in Weld, the last I knew. I haven't been in Maine since 1996, so I've been a little out of touch with the old AUSM gang which was run by the guy who ran Amiga Crossing. It used to be on the main road from Livermore to Portland.
Take a trip up the coast sometime, its worth it. The guy in Belfast had his store in a big old house somewhat off route 1, so you're within easy driving distance of either. Make sure to spend a Saturday or Sunday on Monhegan too, if you're visiting. Grandmas summer home is on Pemaquid Point, so go and see the old fort.
