Even if they do not have games booked people will be shocked just how in demand having available fields are in metro areas just to hold a practice. The complex I play adult rec softball in Clive had to start locking the fields and forcing little leagues to rent the fields for practice because they were becoming so over-run with that. They'd tear up the fields with their practices and the city figured they may as well be paying fees like the rest of the people that use the fields have to so they are helping pay the costs to maintain the fields too. I don't think anyone batted an eye at paying to rent the fields when they did that because they are supposedly so hard to find open fields anywhere around the metro.
Still going to be in Dyersville. Not sure if metro area applies.
