Wilsons Sandbox

I've noticed posts from the Dallas/Colony, TX area and was wondering if there were any riding areas close by. I'm in Plano, TX and am just getting back to dirt riding after a very long absence and wanted to find some place close to kind of get my dirt legs back. Not talking about the local MX tracks but just an area of off road trails. I'm familiar with the Red River area by Bulcher and want to get up there but would like to find some where close by to just get the feel bacl. Thanks
