I know all the teens and 20 somethings are laughing at the "old folks" talking about falling....but... it is a danger. Sometimes it's not just bruises, but a near death drowning, which is nothing to laugh about.
That being said, I continue to rock hop, with caution. It's part of the fun of flyfishing. I look both ways before I cross the road and I look at the depth of the pool before I wade or climb the rocks. Could I get hit by the tractor trailer truck or drown or break a leg? Yep. The alternative is to stay locked in the house all day. Die of boredom.
I don't take foolish risks anywhere, especially in the Park where help may not be readily available. Isn't that the only way to get some "life" out of living?
