Lucky for Lincoln residents that Cinco de Mayo fell on Tuesday this year. Food Truck Mania! visitors Tuesday were treated to a dance performance by the Chinelos de Guerero group in BeermanPlaza as part of the monthly downtown event. Food Truck Mania! is sponsored by the Downtown Lincoln Association from 5 to 8 p.m. the first Tuesday of the month on Fifth Street and BeermannPlaza (645 5th St.) to promote the downtown area.
