I went hunting for ducks near the house the big boar was breaking into. The season is over since Dec13th but, the bait pile was ripped to pices. Logs were scatered everywhere. The bear did come but sometime after the season closed. There is fresh sign in that area now. The weather warmed up this past week, it was in the mid 50's nearly every day.
I read a good tip that I used after I already had bears on the bait.
Dr Ken Nordburg has a great book called "Black Bear baiting and hunting"...awsome book.
Anyway, it said to make a grease line by painting the grease on the tree trunks for 1/2 mile north and 1/2 mile south of your bait. The idea is that you have a 1 mile long scent trail and you bait pile is at the center. The typicaly westerly wind will create a scent cone that covers about 1 1/2 sq miles downwind of your bait.
I had 1 sow and 3 cubs hitting the bait before I moved it to the center of the property. When I moved it I used the mile long scent trail idea (only made it about 1/2 mile long) with a bucket of grease and a paint brush. The next day ALL the double amount of bait I used and ALL the grease (about 5 gals) where gone. and the day after that, I saw a different sow with 2 cubs. The bait went from 4 bears to 7 bears useing that trick the very next day.
If you're lucky enough to be on private land and can leave your stand up during the off season you can tie an old piece of cloth or something of the sort to your stand. I like to use an old camo bandana that I have. That way the deer get used to the movement and eventually don't bother even looking up when there is slight movement. This may just give you the time to draw your bow or raise your gun without being detected.
