One of the nicest facilities we use is Marchant Stadium in Lakeland. They have a fairly large and smooth asphalt parking lot, some trees for shade, and indoor restrooms! Very easy access from I-4, this is one of our favorites! The address is approximate. We enter via the SW corner of the parking lot off of Gilmore Avenue.
We also do events at the Marion County Airport (between Dunnellon and Ocala. This is a restricted access site, you MUST be pre-registered to be allowed on site. You must also arrive at the specified time, or you will not get in the gate! Access to the site is via SW 147th Court off of CR-484. This one is a bit of a drive from the Tampa/St. Pete area, but still only about 90 minutes from downtown Tampa, and about 60 minutes from Brooksville. It has an old runway with a mix of smooth concrete and less smooth asphalt, plus a freshly paved access road that often adds to the course. It presents many different challenges for the driver, and is a lot of fun!
The Venice Airport Festival Grounds is another secure airport facility, pre-registration is required. It’s got a section of old runway with a mix of smooth concrete and asphalt, as well as some usable access roads that make for interesting courses. Just 6 miles off of I-75 for easy access.
