With many nights of wild camping behind me. I try and get out of sight of roads, rails, farms,habitation,likely dog walking routes and other campers. I often use woodland to hide away in. No fires and Bar B Qs. Camp late- 8pm or later in summer with an 8am depart or earlier. Leave no trace- even putting pack ground preenings of twigs, cones, stones.
I also avoid torch use as much as possible as they can be seen for miles and attracts curiosity. I avoid being near water as it attracts bugs; near lakes, lochs it is a colder and often windier; streams seem to get noisier as the night goes on.
