There is a state park lake not too far from D.C. that was made by the Corp of Engineers, dammed the creek & it's great for LMB, bluegill, catfish fishing, etc. The road on the earthened dam is so covered with copperheads that one has to wiggle the rod tip at them before every step in the summer just to get down to a spot on the deep water. A fishing friends wife, who out fished him regularily used the lakes outhouse on an outing & after about 3 minutes let out a blood curdling scream whilst slamming the door wide open & running, almost in her birthday suit from a big 5 footer that had made it's way inside! Seems it was in the fall out west on a small Colorado river where a whole bunch of baby rattlers were swimming in wet wadeable trout waters. Don't know where the mama rattler was, but the blind mans cane practice on the copperheads from back east really helped; even though it was easier just to flick them up on the stream bank with the rod tip being that the rattlers were alot smaller than the copperheads. Of course coeds sunning themselves on big flat rocks in the middle of the stream really didn't believe my stories of swimming rattlesnakes
