I love minor league baseball for all the reasons already mentioned: the bargain prices, the small-town feel, etc. Around here (Western Mass.) the closest minor league parks are in Pittsfield, Massachusetts (formerly NY-Penn League, but this year it’s going to be an independent league) and Connecticut (New Britain, New Haven, Norwich–all AA teams). There used to be a team closer (Holyoke Millers), but that was years ago.
The only downside (for me) to the minor league games is the large number of hokie non-baseball activities going on: dizzy bat races, annoying mascots, dancing in the stands. I understand that this is probably necessary to keep some people entertained, but I just find it ridiculous. When I go to a baseball game, I want to watch a baseball game, not do the wave, the Macarena, the YMCA, the chicken dance… Nor do I want to watch a five-year-old child run around the bases between innings in a “race” against the wacky mascot of the team.
All in all, though, yes, I love minor league baseball. Going to a Red Sox game will cost me$10 for gas, $3 for tolls, $20 for parking, $50 for a pair of tickets (at least), plus another $20 for snacks, and maybe another few bucks for dinner or a cap or something. Compare that to dropping $7 to $10 for a ticket at a minor league game, with free parking in some cases, and I think I can tolerate the little annoyances I mentioned above.
