Hunters Hideaway is next town over from him and a Hoyt Dealer, I was here the other day good guys and a ton of Hoyt bows in stock. Shooting range indoor and outdoor to try bow as well, can shoot from 20 yards to 100 if he wants to get crazy.

Brian's is a great archery shop but probably farther then he wants to travel plus they are a mathews dealer as of this year.
And Kittery has a lot of bows but once again it's a hike plus another 20 min north of Kittery and he could go to Cabela's.
Hope this helps...
