Its not done yet, but I am making a Google Earth map of the riding areas in and around Oklahoma. This is useful especially to GPS users because you can just program the coordinates into your GPS.
There are still a number of them that I don't have on there such as Anadarko, Cogar, Ada, Rush Springs, etc. If you know of any, post up the location or directions to the riding area.

Oh, and of course, you need to download Google Earth to view the file.
