Well I guess you are already in the lovely state of Colorado, but in case you check in here...
If you are going to the casinos be prepared for the lack of table games and the abundance of slot machines...:com: If you play poker, there are only limit games and the country bumpkins at the tables might scare you a little.
Boulder - lots of good places to eat and drink. If you like fish I would suggest Jax. The people who run this restaurant also run Zolo and the West End - all great places to eat. Exam week in Boulder so the nightlife is fairly relaxed right now.
Ft. Collins - again if you are a seafood lover, there is a restaurant there called "Fish" that is one of the best seafood restaurants around. Always good live music in both these towns too.
There's not much in between all these places except for scenery, so enjoy! We are supposed to have a little relief from the cold weather this weekend, should be nice!
