Nah, man, it's increasingly easy. You get thots in the woods and especially if they have no cell service to post their vain photos to Instagram, they are very easily talked into all sorts of photo ops. Modern women can't even begin to comprehend not mugging for the camera constantly, the more trashy Kardashian the better. Being /out/ gives them some kind of excuse to preserve the moment with something memorable.
Also, bring baby wipes. A lot of thots aren't much for trail fucking (no satin sheets I guess) unless they're glamping, but if you clean yourself up a little you'll definitely get blown. Seems primarily because they get bored easily and need to re-establish some kind of affirmation of their sexuality while outdoors, and have something to talk about with their thot friends about how cool they are for doing it innawoods.
