Spotting and stalking is a skill but is easier than you think. takes practice but it gets done.
First thing you need is patience to move slow once spotted a animal and you find your route.
Snow is not a major obstacle. You need some kind of really warm clothes to do it though. Something that will take the cold out of your legs when doing this. If you have to stalk get on your knee's for the last 150 yds and when moving dont pick up legs and set it down. Pick them up alittle and slide them threw the snow and push it out of your way. Do it slowly at ground level and the sound will be minimal. Takes a little practice but works. You will need very warm clothing. I have done this till my knees where no longer cold but felt like they where on fire. Till I learned on the clothing.
Next I archery hunted my first year and used to hear that tale about putting the wind in your face always. Believe me I put on over 50 stalks that first year with this advice and came up with over 70 days of hunting. Finally getting a 138" muley by accident heading back to the truck with my brother.I am not saying that the wind in the face is wrong but it does not work for me. I hunt when it is windy out and love it the windy the better. You will find the bucks bedded with the wind to there backs. They will be facing away from the wind. Come in from the side of them. Forward danger as it comes around will be less danger till they are down wind no danger as they can smell you. There is where patience comes into play. make sure as you are moving you glass totally around the buck. Look for other deer. I have made this mistake many times in the beginning of getting tunnel vision and jumped a deer to blow a long stalk. You will get this down pretty fast if you can take the time on them.
Sometimes it takes a few days or weeks to wait for a buck to get into the right position to get on them. Hopefully you have spent time out learning the areas you will be hunting. This is also a key for hunting them. Different ways they come and go. Where they go into if jumped from one area to the next.
Also if you do spook them do not move till out of sight. Dont get up or move. They might or will just write it off as they where spooky. If they dont haul butt out of there then they will go over the next rise and bed down again if mid day. But if they know you are there then they will get out of dodge.
Good luck and keep us posted.
These techiniques have and does work for me in my area's I hunt. Hope you smoke the buck you choose.
