I have found that it is cool because I can bring people with little experience with me on rivers I couldn't bring them kayaking on with no experience. It's pretty sweet to be able to take my dad or my front ranger gaper friends out onto my favorite rivers. Also, you have to admit, rafts can hold tons of beer! I still kayak too. As far as I'm concerned as long as I'm out on the river on something, I'm a happy dude.
I'll be sure to fish your ass out of there from the raft, so long as you let me hang on the back of your kayak when I swim by holding my kayak!
