I had a few minutes to look some of this up. If anyone is interested, it's Tax Map 150, Parcel 014.11 of Marion County. It looks like there isn't a public roadway that connects to the WMA. It's accessed through Tax Map 146, Parcel 001.00 which is owned by Thunder Air, who just recently purchased the property for $10,750,000, recorded in Book/Page 549/321. The gated access was probably part of the deal for the purchase because they didn't want the liability or were tired of the ATV's being there. Basically, there is no longer public access to the parcel.
