I like the inventory factor...
I never seem to get more than one pic of any good buck, seems I educated him/them!

I will usually spend my camera months from Dec-Feb then get out of the area. Winter is great with snow on the ground to locate the buck beds along with Doe beds and when you connect the dots you will usually have a great rut spot somewhere in-between.

A buck will only tolerate intrusion once or twice then he will pattern YOU!!!
