When I was a youth, I helped the local baitshop guy trap minnows down by Mandaree. Sweet mother of Jesus if that area wasn't snake infested. We used homemade traps that would often catch 5-7 gallons of minnows at a time, so we would have to literally run from the shore to the truck about 60-70 yds up the hill to get the minnows into the old freezer before they'd start to die. Several times while RUNNING I would see a snake pass under my feet. Stupid...I know, but none ever struck out at me. I think every time it was when I had empty buckets and was running down hill, so must have been going too fast. Not so sure I'd have been as lucky if I had run over one going up the hill with two full 6 gallon buckets. That was the slower leg of the journey.
