Don....Your electric fence shock reminded me of a friend of mine....Sr. yr. of high school..Dale, my friend and I took all our camping and fishing gear and drove an hour to a lake to rent a row boat , row to a campsite along the bank and then spend the night and next day fishing....We set up our tent and everything else and I was getting my fishing pole set up....All of a sudden I heard the most blood curdling scream and then a lot of expletive deletes...and here came Dale bent over and moaning....He said he peed in the woods and something stung him...I went to look and found the electric fence sign hidden under some vines...He had peed directly on the electric fence...He had to go home...so he sat down while I broke camp , loaded the boat and rowed back to turn the boat in....just 2 hrs after we had arrived.....I don't remember if it turned out serious or not...I dropped him off at home and I'm sure he told me but it has been 50 yrs...long time...
