At 6 p.m. on Friday happy hour at City Park means an intensive boot camp lead by Chris Lindley.

“These are adults having a wonderful time in the most beautiful park in the city,” Lindley said.

They could be athletic warriors or mothers with strollers, but exercise classes in city parks are all the rage. Now city officials say commercial activity in parks should require a permit and fees. Parks and Recreation officials say the ordinance has always been on the books.
