We had a meet at the Green Dragon a few years back.
Enjoyable, I think, but the owners got a little greedy when we wanted to go back and do a repeat a year or two later.
At that point the grass field behind the pub wasn't set up for camping or motorhome stuff, think they'd (sort of!) cut the grass specially for our meet.
They weren't bothered. They'd owned the pub for quite a long time and had made enough income in that time to not particularly care whether we were there or not.
The Hardraw waterfall was also part of the property and they charged folk an entry fee to walk up to see it.
The grub was pretty good though
No idea what the new owner will do with the pub.
