@G Dinkins I feel your pain, There are a lot of small parks around here(under 500 acres) that only allow ATVs and MX.
There are a few that only allow 50" SxSs.
Then there are the OHV parks that pretty much cater to Rock Buggies.
There are only 4 parks over 500acres within a 3 hour drive from here that allow 60" SXS. The smaller parks are boring it takes an hour to get there and they have about 2-4 miles of trails. Which you can easily ride in an hour.
