Since the city is considering expanding the events at Dehler park, why not let the people who pay for it use it? With all of the little league teams in Billings there should be a game there every Saturday. It would be a thrill for the kids and people would get some use out of the facility they paid for.
Maybe it would feel more like a community facility that way. It was financed by the people, let them use it like your almighty library.
