I dont know about the Mass. part....but can you use scent, or is that considered a bait too?

Scent will work very well if you can use it.

Also, will you be hunting them with a bow or rifle?

If you cant use scent, try still-hunting, or spot-stalk. If you still-hunt you can also use a dying rabbit call or a fawn ball once you spot a bear, and you might be able to call it in. Most the hunters in PA do Bear drives...that works as well.

Finally if you do enough scouting, you may be able to locate a really good hub of bear activity and stand hunt it. They eat lots of acorns in the fall, so they will be near the same places deer are, and they also need to be near a nice fresh water source (creek, river, lake) so that should narrow it down.

Good luck if you go....I'll be in NH bear hunting around the same time.
