On basis of above comments, made Panshanger my destination today and was pleasantly surprised.
The ops room was a little quiet, but the lady in the office behind the desk enormously helpful and friendly. A decent cup off coffee in the cafe too. The runway and grounds are in very good condition....in fact perhaps one of the best grass runways in the SE?
On call up radio was silent. Went back to Farn N and they kindly woke them up for me, but on listening-in prior to departure it became apparent if you are visiting don't worry if your radio call is not answered...join overhead, make position calls and follow the published circuit patterns
