Chris, that is a scary thing! It happened to me on the Colorado River
one time. I know I would avoid the channel from now on...but I would
pursue it further, I would contact the District Attourney in your area
and give him a full report with addresses and such. If they did not at
least investigate the situation, I would contact the local newspaper and
give them the story! Someone should respond to your concerns!!!!
If you raise enough fuss, the idiot that did this might just get the
message!
