I have an offer from the summer, and I'm clerking next year. I really like the firm, but I want to try another city. Maybe this is a dumb question, but is it possible to keep the offer from my 2L firm while working at another firm before clerking?

I wouldn't phrase it the way you did (i.e., "possible to keep the offer"), but I think your course of action--summering at a firm before your clerkship--is certainly acceptable.
