People might complain about Gainesville’s traffic, but that doesn’t mean they’re hot enough to join a city-sponsored focus group geared to finding possible solutions. A Gainesville transportation focus group meeting planned for 2-4 p.m. today at Fair Street Neighborhood Center has been canceled because of lack of interest. “The city did not receive enough applications back from the public,” said Srikanth Yamala, the Gainesville-Hall Metropolitan Planning Organization’s director.
