I have a $240 United Airline credit, where to go?

Without a bunch of boring details, I am not going to the collegiate nationals in Kansas next weeked, so I have a ticket I need to cash in on.

Anyone have suggestions on what to do. I can fly anywhere anytime, but I have to pay for airfare above $240 (willling to spend ~$100 extra). I fly out of Sacramento, CA (SMF).

Anyone have any small weekend (thur-sun) stage races going on in June-Aug? West coast most likely. Anyone want to let me sleep on there floor?

Suggestions, ideas?
