I have killed deer at a watering hole,about 15 years ago I had ascess to some land that did not a good watersource on it,I found a hole about 6ft square and was eat up with tracks so I strapped my climber and waited it seems that all the critters came to drink,including the deer,now granted it was dry and water was in short supply but it was good while it lasted.This october i will be hunting a water sorce also because it is usually hot and dry here the only thing is that it is a creek that runs through my entire property so narrowing down that one speicial spot will be a challenge I think I know of just the spot,I guess I'll find out I found this spot after the season closed so I never hunted it before.
