SPOKANE, Wash. -

It is the calm before the basketball storm that's about to hit the streets of downtown Spokane as teams are beginning to check in at Riverfront Park for Hoopfest 25.

Tens of thousands of people are descending upon the Lilac City, where check-in started at 2 p.m. Thursday for the world's largest three-on-three basketball tournament. Braving the crummy weather players started converging on the park to pick up their team packets and finding out where their team's first game is on Saturday.

Team packet pick-up is open until 8 p.m. Thursday and from 11 a.m. to 7 p.m. Friday.

While check-in is already open for business, so is the Hoopfest Store presented by Nike. The store is filled with great, one-of-a-kind hoopfest swag including branded shirts, shorts, hats and basketballs.

Volunteers have been working around the clock to transform Riverfront Park. Progress is being made on Center Court. The banners and signs are all up and new Hoopfest Director Matt Santangelo can't wait for the games to begin.

“It's coming to light, what used to be a two day basketball tournament is now a four day event and it kicks off Thursday afternoon," he said.

This year Hoopfest will be spread out over 42 city blocks, with 458 courts, 6,900 teams and 27,000 players. On Friday evening downtown streets will shut down so crews will be able to assemble all of those basketball courts so they're ready to go for tip-off Saturday.
