When Gabriel Romero sees the squealing piglet, his eyes light up and the red dog painted on his cheek crinkles as he smiles.His mother, Gina, watches from nearby.“He just seems to be happy with everything, but he likes the animals a lot,” she said as Gabriel toured the animal barn Monday at the Clark County Event Center at the Fairgrounds. His visit was made possible through Memory Makers, a program now in its 15th year aimed at helping medically fragile children enjoy the fair.Gabriel, who has autism, and his mother spent the day with volunteers from Clark County Fire District 6.Wearing flip-flops and sporting a buzz cut, Gabriel followed his mother and a group of three firefighters through animal barns, food courts and lines for rides. Gabriel jumped, waved his arms in circles and clapped with excitement at several points throughout the day.His mother said she didn’t think she could afford to bring Gabriel to the fair this year, so being selected for the program was extra helpful.The program matches three firefighters with two families a day for three days. And more firefighters want to volunteer than the program can support.One of the firefighters, Scott Taube, ended his shift on Monday at 8:00 a.m. and came to the fair to volunteer on his day off. He said part of idea of the program is to support the families of the kids with health issues.
