Our Deer Saga

The deer this year are everywhere. We need my brother to return for a visit because when he was here last year we did not see any on the property during his entire visit. Could they know he is a hunter?? So we have these things called "scarecrows" around our planting areas that are outside the fence. They are attached to the water hoses and when there is movement they go off and spray water suddenly in a large arc. This morning while we were still in bed BJ heard them going off and when he went out on the deck to look there was a deer just standing there getting sprayed with water but eating anyway. Could they be getting conditioned or just plain smarter than us? A neighbor gave us a deer repellent that is a radio that is turned on when it detects movement and then you hear either music or voices. Today we saw two deer walk past this device and stop and listen and then begin to eat. Maybe they liked the station we chose. Good grief.
