Anyone ever see a course that used "grass pavers" for tee pads? They are plastic grid panels or rolls that lay on top of a thin gravel or rock base and then is filled with more gravel. They are less labor intensive since you don't need to dig as deep or use as much rock base. There are several brands out there. I was looking at HexPave. The same company has a heavy duty version called EasyPave. Another company has a rolled version called NDS Tufftrack Gravel Paver. Cement pads are a very difficult option in the middle of a hilly forest.
