I spoke with Ed after he landed and got a NOTAM on the runway.
As he mentioned in an earlier posting, Runway 28 is generally preferred. He said that the portion from the first marker cones is usable for landings. That's about 200' before the threshold cones for 28, and 50' past the new grass (aka dirt), which is too soft to allow landings yet. It is suitable, however, for taxiing and takeoff. So the new, unmarked threshold for 28 is 200'.
If you're coming in after this weekend, 8/5-6, check with the airport manager for a current NOTAM, since it's expected to improve.
