Yes, rolling. But steep enough that land-out options after a low aerotow failure when one can't get back to the airfield look pretty scary. I remember discussing them with one of their instructors last year when I got to fly thier DG1000 and it really didn't look nice if one was just over the boundary...
And also on top of a hill enough that it drains very quickly after rain.
But I wasn't meaning to imply it has soarable ridges by saying it is a hilltop site!
