white water rafting?

My friends and I are planning to go to Cagayan de Oro this coming April and will try this super extreme (at least to me) white water rafting action. I think i'm gonna puke just by the thought of it. I can't even swim, let alone riding a raft in a raging body of water?!? Ulk! That sure sounds interesting huh but what if i fell and knock my head on the stone? Ulk again! But guess what, i'm still going with the group. I can't miss this outing. I'll find a way to enjoy even if i'm not doing the rafting. Or who knows? I might be convinced when i get there. :) After CDO, we might go to Iligan or Camiguin. I'm excited! :P
