What Should I Do?

I have friends flying in from Texas next week to hang out in Albany.

I do have a couple of things planned already (State Museum to see the 9-11 exhibit because my goal is to make people I love and care about cry over a tragedy and some food venue related places, Wolff's for the World Cup, Lionheart for Happy Hour to people watch, the Palais at 3:30 in the morning, et cetera, and one of the days is being taken over by a trip to the Berkshires.) but I am looking for more options.

What would you do that is fun and cheap in the Capital District?
