@CarlsBeef Butterfield Park in Elmhurst has what you’re looking for. South Elmhurst so closer to Oak Brook/more centrally located.
Covered pavilion, picnic tables, grill, bathrooms, and a baseball diamond to get any necessary fieldwork in.
@thekapman@LouMalnatis Caleb can absolutely pass Walter for #2. Obviously, a lot has to go right, but if anyone can, a successful qb in Chicago can.
MJ, Sweetness, Kaner, top 3, with the 4th a toss up between your personal fandom. Scottie, Frank Thomas, Ernie Banks can all make a case.
