15. Municipal Stadium
Hagerstown's Municipal Stadium, originally built in 1931 and renovated over the years, has exactly zero of the modern amenities associated with modern minor league ballparks (not even an outfield playspace!). What it does have is a quaint covered grandstand and a small hill in leftfield, the result of a limestone deposit they've never been able to tame. Sometimes the joys of minor league baseball are simple: a cold beer, some shade for your head, and taking bets on whether that 5-star outfield prospect tweaks an ankle running out to the field between innings.
