Take in a Cape Cod League baseball game
The Cape Cod Baseball League (CCBL) produces more big league baseball players than any other summer college baseball league in the entire country. Not only is the baseball quality, but the atmosphere is great. All games are free of charge and while most stadiums have bleachers, fans are encouraged to bring their own chairs to sit on. Note: these games do not serve alcoholic beverages. I repeat: baseball without beer. My one and only gripe.
