I'm told that in some midwest states, a lot of hunters would hold down the top strand of barbed wire with the forearm of their guns while crossing. I got that as an explanation of why I've seen so many guns with forearm wood that looked like a beaver chewed it.
In my state, I've observed most guys pressing down the top strand with the gun's buttplate... which might explain very worn and scratched buttplates on otherwise decent looking guns. No doubt there are more fences to cross in the East, but there are lots of ways people find to abuse their guns.
I usually use my hand on the top fence strand, and save the buttplate, except on electric fences. A word of advice: Don't let that wire slip while you are straddling an electric fence. If you do it in the East, they will hear you out West.
Brings back bad bad memories.
Two years ago crossing an electrified fence that was placed about 1" inside of a barbed wire fence in the dark while turkey hunting. There were no cows in there, so the owner told me the electric fence was off. HE WAS WRONG
Anyway, got a late start and the birds were gobbling as I was trying to hustle across the fence. Had slid the shotgun under the fence and was trying to climb across. No light being used (bird gobbling didn't wan't to give away my position). Standing on the second strand of the barbed wire fence and then swung my other leg over so it was on the inside on that same second strand. Then swung my first leg over so now I'm got both feet on the second strand on the inside of the fence. Then took my one leg and reached for the ground. Leg touched ground and then I tried to step down with the remaining leg off the wire.
Remaining leg catches on barbed wire, I loose by balance and fall over. While falling over the leg caught in the barbed wire is now resting against the electric fence. Not a big deal in my mind as I just need to free my leg and the fence isn't hot anyway. WRONG. Then the first jolt hits me.
Many folks don't realize an electric fence essentially pulses. One shot of juice and then a half second break and then another shot of juice.
Now I realize I'm in trouble. I'm on the ground, leg in the air caught on the barbed wire fence and that leg is resting against an electric fence. I try to jerk my leg off the fence, but I can't, so I just get shocked and shocked and shocked. Now these fences are made to keep cows in that have lots of fur, so they are juiced up to get a cows attention. With lightweight pants on I have zero protection, so I'm doing the dance. I scream and then laugh (it's a bit funny) and then I get hit by another shot of juice and I scream again. Eventually more screaming then laughing.
I'm digging around in my pocket in the dark trying to find my knife and finally free it and rip it open and cut my pants free from the wire and hit the ground and its over.
PS. Never did get to the turkey. I was a pretty much a wreck by the time it was over and just went and sat in the woods and tried to get myself back together.
