The National Biker Roundup hits the Boone County Fairgrounds
In addition to the extra revenue coming to the city, one group of riders came to give back in another way.
God's Wheels has been attending the National Bikers Roundup for about 20 years, and each time it gives back to the community it visits.
"We thought that we would leave a piece for everybody, and we said food would be the thing," said God's Wheels National President Harry Gumby.
The group is collecting food and cash donations throughout the week. All of the food and money raised will go to the Central Missouri Food Bank. The goal is to beat the group's previous record of 95,000 pounds of food.
And because there are so many visitors, security officers and police are directing traffic at every entrance to the fair grounds.
But on the inside it's a much different atmosphere. There are R-V's, tents, vendors and bikes everywhere. Attendee's pass the time cooking food, shopping and hanging out with friends.
And the roundup isn't just for bikers.
"I've never been a motorcycle driver, I've never ridden one. If you've never been to one, come. You've got to come to one and once you come to one you'll keep coming," said NBR attendee Ronda Martin.
There are three stages set-up for concerts this weekend, but the main draw for most isn't the entertainment.
"Just the famliness of it, the warmness of it, I get to see everybody again that I haven't seen in a year," said NBR Chairman Billy Walker.
And even the vendors aren't at the round-up just for business.
"It makes me feel good to know we actually come together as a group, you know it's not all about the money," said vendor Clifton Brown.
Biker Barney Huggins hasn't missed a roundup since 1995, he says, "This is nothing but a big family reunion, cause guys I've seen 15 years ago...I get to see them here, and if I don't see them here, I'll see them next year."
Brown says everyone should come out to see what the round-up is all about.
"Bikers are a different breed of people, you meet a biker, you've got a friend. I've got people here today that I met six years ago," said Brown.
The roundup runs through Sunday and is open to the public. General admission wristbands are good for the whole week and cost 25 dollars.
