recently in my area we recieved 3-5 foot of fresh snow.how does this change things such as how far they will come to a call,home range travel,if they stay on a food source.I live where their is rolling hills dairy farm land.some long range shots some short.I set up in open pastures and fields next to big woods and brush lots.I killed 2 using a JS 512 ct distress lastyear.I now have a foxpro 16.all the locals have them call shy on ct distress.any sugestions? thanks 30cal
