"Clark Field"
Unusual because there was a 12- to 30-foot limestone  cliff that ran from left-center to center field that making playing the  outfield adventurous. The cliff could only be accessed via a goat path. Centerfield was nicknamed “Billy Goat Hill.” There was a scoreboard on top of the hill, in the field, in front of the fence that could cause even more weird bounces for outfielders.
Outfielders could chose to play on top of the cliff or chose to play in front of the cliff.
