I also love going to Red Sox games (I am excited for the new season to begin). I love the feeling of watching a game at Fenway knowing all the great ball players that have been there. I also enjoy football and hockey. If you are not a sports fan it's definitely not a deal breaker though!
Other interests are: Going to museums (I make excellent use of my MFA membership), camping, hiking trying new foods (I am a bit of a foodie), and great conversation. I have a lot more interests but where would the fun be if I just typed it all out for you?
