I'll be staying at the sheraton gateway hotel over by riverdale road in atlanta on the 26th, 27th and 28th for work training. Any reasonable places to ride in the immediate area? 25-30 miles would be a good ride... probably bring my mtb with 90psi 26x1.25s on it. I could drive a bit to go somewhere else, but I get lost trying to get out of a wet paper bag... will be riding after 4pm. Riverdale is a pretty nice road, but seems like it gets sketchy over by old national highway. (this is my 4th or 5th trip to the area, first time w/ a bike tho)
