You're not the one hanging around the lambing sheds at 3 am covered in birthing fluid and wondering what that noise was...
Good point, well presented

I always sleep light... even after a good skinful of various hip flasks and a good size group.
If i hear a noise, thats me awake for an hour.
Need to do this solo thing soon. I guess its just as important to find somewhere you feel really comfortable with the surroundings aswell. Spend lots of time there in the daylight, get to know the area, maybe even try having a kip for an hour or two on a weekend lunchtime as its now warming up...
