Indianapolis / Carmel free outdoor cages
Central Indiana families usually get free outdoor reps on park diamonds (Carmel Clay and similar). Grand Park is a destination complex — cages are typically event/rental, not free walk-up.
Access tip: “Free outdoor” usually means a public park diamond or walk-up cage with no token machine. Leagues often reserve cages for practice. Bring a helmet, your own balls/tee when allowed, and always confirm posted park rules.
