i can understand why people wouldnt ask for permission,if you get turned down realistically that wouldn't stop most people,except then the land owners know exactly what you look like.
the people who steal from keepers,break fences etc etc f**k it up for everyone else,ive never taken anything that belonged to someone else while out with the dogs,my dogs mean to much to me to risk them getting shot for one thing and also im not a thief.
