text: Yes, it's more the 'rural vs. urban' thing, but basically roads up here are only constructed a few ways, and basically if it's county then they'll do the whole gravel road base and a sealant, for driveways/service to people's homes, those could be just compacted soil/earth.  This is 'my neck of the woods' so mostly this is all imported tiger and when I began fixing it all up I wasn't real aware/concerned about the surface tag; coming back around to it...
