If you guys like beer as much as I do, the next time you're in Portland you should check out Downeast Beverage (on the waterfront). Sheesh! Probably the best selection of beer I've seen in Maine. A lot of great Belgian beers (which I love, having lived in Belgium for 7 years).
And they have a stand in the entrance where you can "make your own six-pack" of micro-brews for only $7.49.
