We have been to Falmouth, Chatham and Orleans. We come every year (perk of having family in the area). We like Orleans out of the 3 because it's the easiest to get a foul ball (my kids goal/wish each year). Especially if you sit on 3rd base foul line, it's less crowded than first but don't tell anyone because we plan to be there this week too and is already talking about getting another one . He always gets players to autograph as well.
We will be going to the Y-D game (on Wednesday 2nd) since the Ags are mostly upper cape this year. To catch the transfer- Chris Hacopian (Y-D)and the Ags at that game- Harrison & Ben Royce (Falmouth).
It's free to go. Bring chairs as most don't have seating (Chatham does!) and cash to support through raffle or snacks. All the different parks start at different times. Stay after and you can catch some autographs and we always talk to the Ags to let them know we're Ags too!
It's always a great time and we've been doing it since I was a kid. A few we have met in the recent past Kaeden Kent, Tabb Tracy, Logan Britt (gave my then 5 yo a bat and he still has stars in his eyes about that), Trevor Werner, Ali Camarillo, and others I can't remember at the moment.
