Here is some info and shots of my setup.
Tree stand, facing east for optimum filming light, bait is to the east about 15 meters along an old fallen Jackpine. to the south is a muskeg of black spruce that is a start of a creek that runs to the east. the stand is on a wind fall area of a Jack pine ridge that is fairly open.
Bait is oat and dog food with a mix in of treats (breads, meats and sweets). just east of the bait is a scent bomb of sardines, oils and sawdust that has been socking and fermenting for about a month.
Two days into the season and no bear activity yet, but very early spring for here so, bears might still be using "the length of day" for coming out of the den, also very little food to support them out of the den for any length of time.
I did not hunt tonight due to no sign but will keep a careful watch, and will do more consistent sitting come early may.
