Looking at river rafting in Glenwood Springs, CO this summer. I've rafted before ... decades ago when I was a youngster and much less fluffy. DH and DS have never rafted and would love it. We aren't going to do a full-day, big-time rapids trip, just a one or two-hour, some gentle rapids but nothing too crazy. I'm mostly wondering about getting into the raft and any lifejacket that might be required. Any fluffy folks rafted recently?
