Create your dream autumn holiday in Prague. Bad Religion, July 30. Aura, Portland, $32.50 in advance, $38 day of show. Some concerts also feature Food Truck Friday and a free Kid Zone. There are several open air concert series here in Geauga County in 2014. The $20 tickets have no hidden fees attached, and they aren’t a one-off gimmick – rather, they’re smart business strategy that also pays off for fans. We found that.
