First time going to Boston and New York tips

looks like we are going to be able to pull off a back to back trip to see Boston play at home and then the Yankees play at home.

Boston is a Friday night game and New York is a Saturday afternoon game

just looking for any tips you all have for visiting the stadiums, whether it is where to park or taking public transit

going to be staying in Newton for the Boston game and then down at Newark for the Yankees game to fly out the next day
