Add me to the list of people that found your post thought provoking and timely. I'm still feeling guilty over a swim I had in a run that I had no business being on. Friends and unknown friends had to pull me out. I hate to even think about it, I still feel like poop about it a year later. I'm gaining experience every year though and I have a much better idea of the things I won't do.
I want to have fun, not be scared for a whole run. Thankfully my boating buds dont' give me a hard time if I'm gripped and walk. Well, they might give me friendly shiat, but I know they're kidding.
I wish there was a rating system for experts and a separate one for newer, non-hair boaters. I now know that Tom Chamberlain's class II-III is my class III-IV. Does that make sense? The same goes for flow colors. Usually if its green, its big in my book. A whole other topic I suppose, but pertinent in that just going with the guidebook's rating can be misleading to us newer boaters at times.
Thanks again Dan.
