I got a 2 person IK a couple years ago... awesome boat & lots of fun.
I am a part-time raft guide in Glenwood Springs as well. The company I work with WhiteWaterRafting LLC (Colorado Whitewater Rafting) rents single & double IKs, and also offers guided IK trips.
I love getting out in the small boats and would be happy to spend a few days boating with you. We still have a healthy amount of water running in the Colorado and Roaring Fork rivers still with ~35miles of river between 500-2000cfs Class I,II, & III. I believe this is the best water you'll find in the state this season. Also, I live in Carbondale, and there is lots of other fun stuff to do out here... its a unique town!
