Well this is a good subject.I used to urine where ever then i got this idea about a gatorade bottle.unfortunateley ive been seeing less deer.i'm starting to think its because of all the movement of dealing with the bottle. i,m going back to let it hang then sit still.(little movement as possible. Deer might not care about urine but, it's a fact that they care about that person they see fumbling too fill a bottle)
