Ok, this stretch of the Provo is a booze cruise. Bear bridge is the only obstacle to look out for. You can't fault the man for being in a Walmart raft, pretty much everyone else is. He was just unlucky to break his oar at that point. But he probably should have had the cents, to walk around with a small kid and lack of experience anyways.
On the weekends there is 50 to 100 people partying on a island a mile upstream. Makes for quite alot of carnage at the bridge when the twenty tube, tied together floatilla comes around that corner.
