I have a feeding station in my back yard for deer and I check it occasionally to see if there are any out there. Sometimes I actually catch them there and I enjoy watching them. For the sake of not making wasted trips out to the porch to see what they are up to I was thinking of getting a driveway alarm that would let me know when they are there. Does any one have any experience with these products that give some advice? I was thinking that some sort of beam across the game trail or across the station would alert me.
