I am from Jacksonville, there a couple of guys around here that have ridden there too. Do you know any of them cause that picture looks familiar.One decent spot that I have been going is Near Talladega. Its located near Brecon Road, can't miss it. It wil be labled on google maps as Anniston Army Depot. It at one time was used to store munitions. There are many old bunkers still on the site. The park land was acquired through the federal lands to parks program of the US Dept. Of the Interior. Below are a few pics.
