The original post indicated that I looked at Airnav.

My home airport main runway is listed as narrower than my wingspan. The cleared area is much wider than the published width of the runway so am able to safely operate there.

Would like to know if Thunder Ridge is the same. Could fly my super cub up and take a look but it’s a long way at 90 knots.
