You are cute! I live 45 mins north of Boston and have been to many many red sox games! You have to get him GREAT seats. They are pricey but really they are worth it if its a dream trip! Its too bad the price of gas is sooo high, my ex was a huge yankees fan and we used to fly to NYC for a day to see Yankees/Red Sox games at yankee stadium a couple times a year. It was only like $55 round trip for the 45 min flight. Not anymore unfortunately! If you ever need help with tickets and stuff let me know. I might know some season ticket holders!
Your hubby sounds nothing less of 100% deserving of his dream trip!! He sounds like a wonderful man who loves you to pieces!

Lucky girl!
