Yankee,
I have heard a lot of horror stories about bear hunting in Maine. I know a lot of guys that have hunted Maine for bears and they see few if any bears and they are usually on the small side. I would go for the pronghorn hunt myself. If you don't have an outfitter in mind, use a booking agent like Bullseye Outfitters and let them put you in contact with a reputable outfitter. I booked a few hunts with them and have never been dissappointed. Good luck! www.bullseyeoutfitters.com
