With who did you book? What area? I helped a guide near Machias for a few years and had a lot of fun helping with baits and running dogs.

As far as advice, be as scent free as possible and sit real still. If you are hunting with a gun.. set up at least 50 yards away, if with a bow... let them settle down before trying to draw. Also, don't be afraid to bring a bottle of maple syrup, or save bacon grease the last month or so of the summer to add near the bait you sit. It worked for a few guys in bringing some of the bigger bears who were waiting till after dark in during shooting light.

Bring a fishing pole, as bear hunting over baits leaves you free time during the day. May be the most relaxing hunt you could do.
