He can't go wrong playing in Keene. It's my favorite non coastal town in New England. Very safe although a 19 or 20 year old might find it a little boring. As mentioned above it's an older stadium but has a great atmosphere. For an area that's not big on baseball they get a very good crowd. He might have 4 away games within an hour and a half bus ride, the rest will probable be 2-1/2 to 3-1/2 hours. Good luck!
