I'm in the Lower Mainland, and i'm going to be trying to hunt snows for my first time this season. I will be hunting from a layout blind, using a small spread of ~60 decoys (shells and socks). I have a snow call.

Any general tips to help a noobie out?

Also, is mixing light and dark decoys feasible? If so, i could increase my spread to ~100 decoys.

Thanks!
