Keep it low key. I do a lot of places that the public use during the day, but at night it's just me and a friend. Cover your tracks, don't leave any corpses or blood, litter, even fag dimps, cos if folk are owt like me, they'll spot the dimps! I notice these when poachers have been on a local private reservoir. Leave the area clean and nobody will know you've been. I'd still go if I was you, have a word.
