I did two tours at Ft. Hood, Texas, as an MP. I was in the traffic section, so could go anywhere, and had no specific patrol area. I saw and killed a lot of big rattlers that came out on the blacktop to warm up at dusk. Never saw over 11 rattles on any of them, but they were rather large in diameter. One area of west Ft. Hood was off limits to training exercise , and the number of rattlers there was considerable. I hunted dove there and on more than one occasion killed five rattlers on a single hunt. When retrieving doves it was a good idea to watch your step!! Plenty of Copperheads there also, and the wife mowed a coral snake in our yard once. She wasn't too impressed with that, since we had two kids under five at the time, that played in the yard.
By far the snakiest place I've ever been was Knotts Island, NC. I was in the Navy and stationed at NAS Oceana Virginia at the time, but lived on Knotts Island. The number of moccosins there was hard to believe. My landlords grandson and I would actually hunt them just for kicks. They were the Florida strain and really stunk when you killed them. One afternoon in October Ronnie and I went to repair some deer stands. We each brought along a 20 gauge and about a box of shells each. The snakes were just starting to go into hibernation in the Pine woods we were in, which adjoined Mackey Island Wildlife refuge. Every turned up root system or hole in the ground had several snakes outside trying to sun themselves. We would shoot several with every shot and ran out of shells before we did snakes!!! The woods just reeked. Took about two days to get the smell out of my system. Long walk out with no shells left also!
