Andyj of MyOldRV gives the up (the money) and the down (the snakes, for starters) about oil field gate guarding in South Texas, which seems to be coming back into vogue with the Trump economy.
“‘Never step where you can’t see bare ground!’ What you gotta do is stay out of the brush and tall grass because them buzztails are hidin’ rascals! Keep ALL the area around the RV and Service Trailer down to bare ground. Your service guy most likely has a weedeater and I keep things clean with weedkiller spray. One other thing is to put a light under the RV that shines on the underneath and out on your front steps and porch. Thataway when you step out at night you can see. In seven years I have not been on a single ranch that did not want me to kill every rattlesnake I saw but you still need to ask the ranch manager. I tell folks to get a long handle hoe and keep it on hand by the door outside so you can chop ’em up at some distance. Me myself, I use a heavy walking stick. I pin their head with the stick and then reach down with my knife and whack it off. You do have a knife in your pocket, right?”
