A barricade at Lake Park has been shutting out visitors since early December.
Many of the groups who rely on the park are now getting fed up because the problem that forced the park's closure isn't getting fixed.
A big group of kids and their families with Tampa BMX protested the closure on Saturday afternoon.
The BMX group typically used one of the tracks at Lake Park at least three times a week. Now unable to do so they have been forced to cancel state races. Protestors have been gathering petition signatures in hopes of changing that.
"Everywhere I go, kids ask me, when's the park going to open? When can we come back out to ride our bikes? We want to get out on the track," said protester Debbie Dixon. "We're trying. We want everyone to contact the commissioners, the park administrators, everyone you can (think of) to get the park back open."
According to the county, they were concerned about visitor safety because of a 90-foot sinkhole at the back of the park, and other possible sinkhole activity nearby.
While that area remains fenced off and a study of the entire park is now complete Lake Park remains closed.
At this time, the county has yet to respond on what is causing the holdup of the reopening of Lake Park.
