On our roadtrip, we are interested in doing whitewater rafting somewhere in the western US. We are not 100% sure exactly where we want to do it, but we want to do a 1 day trip rather than a 3-4 day trip. All the sites we can find are trip companies that are trying to sell us trips, rather than information about where is the best place to raft. Any suggestions for places to raft, or sites to look at?
