Nothing and everything.
I parked on this beach on the Isle of Skye at the end of a long track with 20% gradients. Doesn't come easy negotiating slopes like that when you're used to Fen roads...
And as I sat about taking it all in a crofter came by and said was I thinking of staying the night on the beach?
(now theres a good idea...

)
And she said I'd be more than welcome, her exact words were "Help yourself, it's free for
everybody"
I slept on the beach for 5 nights...
