Sacramento - Ethan Dean will be living his dream on Tuesday.The six-year-old has a garbage truck bedspread and pillow. He has garbage truck toys. He's had a garbage truck birthday party.Now, thanks to the Make-A-Wish Foundation, he's going to experience what it's like to be a garbage truck driver. The boy who has cystic fibrosis will ride in a real garbage truck through downtown Sacramento, collecting trash and recyclables, just like he's always wanted.When Ethan visited the Make-A-Wish Foundation in February, he was asked a series of questions: What do you want to be? Who do you want to meet? What do you want to have? Where do you want to go?Almost all of his answers were garbage truck-related, said Jennifer Stolo, CEO of the local chapter of the Make-A-Wish Foundation. He really, really wants to be a garbage man when he grows up.It meant the wish he'd be granted wasn't too mysterious."We pretty much knew it was going to be about garbage trucks," said Ethan's dad, Ken Dean, laughing. He's been watching them come down the street since he first learned how to crawl, his dad said.Stolo and her team of "fairies" knew just what he wanted.Tuesday morning at an outdoor assembly at his elementary school in Rancho Cordova, Ethan will discover his garbage man surprise. Then he and his partner will take off, stopping in five locations for garbage and recyclables, before ending at the Capitol for a press conference and VIP lunch.Ethan was diagnosed with cystic fibrosis as an infant and began treatment at eight weeks old. The genetic disorder is characterised by a buildup of thick mucus and frequent lung infections, and the median life expectancy is about 40 years old.Though he and his parents haven't had a big talk about his diagnosis, his dad said every once in a while Ethan asks him a question or two. He's begun to realise that his friends and younger sister don't have to go to treatment like he does.His dad hopes none of that will be on Ethan's mind Tuesday. The only thing he needs to think about is garbage. And trucks."I want him to have fun and not have to worry about the day-to-day," his dad said. "It's all about him."
