Since you're only going out a few feet to clear brush, you're only going to be in 2-3' water if you take a bath - right? Stand up, get in truck, fix cocktail, post photos and have a good laugh.
Herein lies my fear/concern; 2' off the bank of the dam and I'm in 9' of water, it drops straight down!
The cocktail is needed just to build up the courage to do it
