SPOKANE, Wash. -

For most, Hoopfest is a weekend full of basketball fun, but for those responsible for setting up the world's largest 3 on 3 basketball tournament, it's a messy business.

The numbers are staggering: 7,000 teams, 225,000 spectators and 450 courts spanning 42 city blocks, but the most impressive number might be the 3,000 volunteers who bring Hoopfest to life.

"I mean you just look around and you can see how many of us are out here putting this together," says Amber Williams. She's part of the Lilac City Roller Girls, who did their part by dispersing trash cans all over downtown. "It's a great thing. Spokane gets behind the tournament, is willing to help in any way they possibly can," she adds.

The volunteers come from all over, some from places you wouldn't expect. "We've got a bunch of Geiger inmates who come and do a terrific job," says Site Crew Leader Scott Jones.

By sunrise, Hoopfest will be ready to go. "One thing we can't do because of the rain is tape," says Jones.

The tape crew will start at 5:AM tomorrow and barring any more rain, will ready for tip-off.

Either way Jones is excited saying, "This is an amazing event. Rain or shine, people want to come."
