just like you,
if snow is uncommon in the area,
it will change deer pattern for a short time,
may delay their movement by hours or even a day or so,
and take others advise for trekking in the snow,
6" or so is an easy walk,
12" will change your steps and soak your pants,
dont plan on traveling as far as your used to.
make sure boots are waterproof, and keep snow out the boot,
wet boots/pants makes it really uncomfortable to walk in,
comfy set can hike all day, wrong boots, can be miserable in an hr
