I remember my instructor at Welshpool trying to get me lost and failing most times because I was brought up around there and it's all pretty distinctive.
After one particular bit of messing around with air work:
Instructor: 'OK, surely you are lost by now. Where are we?'
Me (looks down to my left): 'Well, that's Pitchford Hall down there, so...'
Instructor: 'Damn!'
(if you don't know it, Pitchford is a huge black and white pile which was the country escape plan for the royals in WW2)
