My wife and I just completed our 4th summer baseball road trip together and our 1st with our daughter Megan (born in February.) We had a great time seeing my Mets play at Nationals Park and Citizen's Bank and seeing Steph's Yanks at Camden Yards. It was our first trip to Nationals Park and Camden Yards and we have high opinions of both. All three parks were especially accommodating with a 6 month old, especially in (although I hate to say it) Philadelphia. Not sure where next year will take us as we hope to buy a house next spring, but Steph and I are up to 21 in our chase, while Megan is at 4! Thanks to everyone for all the advice they gave us here and on the Facebook page on taking a little one to ballparks!
