The city already has 10."I don't think they need tennis courts. I love the open space, I love the trees," said Cathy Gibbs, opposes tennis courts.Some tennis players think two more courts are very necessary because it's very difficult to get a court during prime time.City leaders say this issue has been before the city council at least three times. The courts were in the city's master plan and several tennis players showed up in favor of the courts. When they saw the protest, they weren't too worried."Very few people when you think of population of this area," said Nancy Saunders, tennis player.But it was enough for city officials to shut down construction for now and call a meeting for concerned citizens with the mayor."The city council is going to have to put heads together and see how to respond to this reaction.
