Some years ago now since I visited in a Pup 100 hp and a C172. I agree the need to take care with downward sloping N-S runway and the hill on the approach. 2 other things gave me some anxious moments:
1 There were some BIG rabbit holes: not much prop clearance on the Pup
2 After spending time in the museum don't be surprised if the wind is completely different to your arrival. Its a seriously coastal airfield with the associated offshore/onshore winds which tend to be stonger than over land. We departed right on the crosswind limits skipping over those rabbit mounds.
