I ride trails on both sides of the state lines in SMNP and, I carry a 1911a1 45 acp and only time I have needed to shoot was coyotes/feral dogs. I have seen bears, snakes, fox, bobcats and those elk they released. The elk are dangerous because they don't fear people like they should. Shiners will want you to buy a quart or 2, cash croppers are dangerous at harvest time then there are the meth-heads and a very few just evil people. that are what you could face but most likely won't be shooting in the park with anything more than your camera. Carry an extra battery and SD card so you can get all the pics you want.
