I dont like being too close to water as the midges seem to find me pretty tasty. I like to find somewhere relatively shelter. Not directly on a track, so behind a wall, just over the ridge, in amongst the trees etc
Most of my kit is alpine climbing related so is not very stealthy. My newest bivi bag is a marmot model that is ORANGE! So its good to be out of the way as much as possible.

It works really well and has been on two trips since I purchased it.
How urban do you go without meeting a load of Chavs or Bagheads?
