Hi. We are visiting Boston from New Zealand next year for the marathon (April 21). We have discovered that the Boston Red Socks are playing the Yankees the next day at home and would love to go to this (we have 2 children 10 and 7). Could someone please give me some advice – where is the best place to buy tickets? Are they on sale yet? Where would you advise the best place to sit in the stadium for people with no real knowledge of baseball? Thank you in advance!
