I did Imlay a few weeks back, had a good time, but I keep seeing that it's rated "4B IV R" which mostly makes sense, except for the "R" rating. What about Imlay justifies a "Risky" rating? Is there something that is only risky with higher or lower water levels, that I didn't experience? Did I miss something? Did I just naively glance over some danger which, if I wasn't careful, would've killed/seriously injured me? Being completely honest, I felt perfectly safe the entire time we were going through. I don't recall any required high stemming with the possibility of a bad fall, I don't recall any big jumps that could go south... Some clarification would be much appreciated. Thanks!
