Thanks for the directions to the Patuxent Visitor's Center. I can't find the place for sure on my map. One person mentioned route 198 and another 193. It appears to me that it is close to 197 which is the road my map shows for Sandy Hill Landfill. Is it the area west of the landfill marked with Goose Pond, Redington Lake, and Harding Spring?
