Crawled about another meter closer from last post. The full approach from standing took 20 minutes. Then I realized this venue (RC airfield) was now open as a big RC jet took off. Now glad to be low for two reasons. Still a large crop. As I was waiting for this diligent sentinel to do something interesting, out popped a head (the mate) still standing well down in the entrance tunnel.
