No facilities (fields, etc.) for inner city baseball - especially Little League.
As to the “no big deal” posts - actually it is a pretty big deal. Williamsport usually does pretty serious vetting of these teams and players (especially after the Danny Almonte incident). In this case, suspiciously, it seems they backed off.
Chicago actually has a pretty good public park system with a lot of diamonds in the greenway along Lake Shore Drive on the South Side. There are places for Little League Teams to play in inner city Chicago. Of course, having a field doesn’t mean they will always follow the rules while playing.
