RE: Bear bomb
Mix up some bear crack and save yourself some money. ( if its legal in your state)
Get yourself a couple bags of marshmallows andsome sort of berry flavored jello mix and put it in an old frying pan. Cook that over an old camp stove and stir occasionally. You will experience a thick white smoke that cascades out through the woods.
If you can locate an already used food source ( apple trees, grains etc.) I would set up in that area, or any other area that the bears are known to fequent on a regular basis.
Honey or bacon burns can also prove effective but I would use bear crack before anything.
Another item that has been used in the back country is a propane torch.( don't light it of course) Just crack the valve to let the smell leak from the tip. The bears goes nuts over the additive in propane.
Try doing a burn in the evening from a ridgetop above the area that has bears in it. I would return to the same spot the next day and try again. If the bears came in from the odor the night before, there is a good chance that they will not be far the next day. Your best chances are at first light and last light.
hope this helps. Sorry for taking so long to respond to this....I have been bear hunting for the last month ;0)
PS- you might want to call your fish and game office to find out if kitchen grease is considered bait. If its poured on the ground they willdig for hours looking for the food
