The rally will include several rides that take bikers along rural highways around the region.
The Kentucky Motorcycle Association has signs posted to remind drivers to "Share the Road" and look out for motorcyclist.
"We've got Highway 60 coming through and County Road 109," said Sturgis Police Chief Dewayne Jackson. "We have a lot of traffic, and we don't have a bypass that goes around. So if it gets congested, just take your time and have patience. And if it gets too congested, we'll direct traffic for a while."
The rally started last night and will run through Sunday at the Union County Fairgrounds.
On the fairgrounds, they're taking part in contests or checking out the concerts and vendors,but they're also pumping money into the community each time they visit.
"Everybody around here is kinda struggling," said owner Carlene Thomas. "So, to have this many people in town buying merchandise, its a great opportunity."
Many of the bikers take part in poker runs over the weekend, which raise money for local charities. The next one is tomorrow morning.
"Just have a good time," said Dennis Brown, "relax, have a good party, good show, get together with friends and family."
"It's a lot of fun," said Mary Brown, "lot of noise, lot of beer, and a lot of friends."
Last year's rally was extra special for the Browns. They had themselves a biker wedding.
