ya i'd have to prob agree with you on that time frame. anywhere from january til the snow leaves is good time around here too. but like you said you need the fresh snow and lots of it. more snow ya can get the more harder it is for them to get food, so if your hunting over bait this is great for the hunter
I agree with the above would would like to add something. The coyote "rut" is upon us and love is in the air....as well as an intense need to defend territory. Now it's time to mix our critter in distress calling with some lone male howls and female invitation howls.
When placing a trail camera don't just look for a well used trail. What you want to do is look for a freshly used trail off by itself that goes from a north facing ridge, thick forest, brushy knob or some other similar bedding area to a food source. Don't forget water sources. Especially in the summer months the deer need water so look for a good trail going down too a creek surrounded by thick cover and place the camera 100 yards up from the water source.
Scent control is very important...
