Our last UK camping holiday was to Tenby. We had one of those big frame tents, not designed for extreme weather. But it was August so should have been OK
For those that can remember, it was 1979, the time of the Fastnet race tragedy. The wind howled but the tent survived. Until one night at about 4am my Dad woke us up and told us the tent frame was buckling under the pressure and it was pulling the tent pegs out of the ground.
We stuffed everything in the car (I had to have the cooker on my lap all the way back to Lancashire) and when we left at 6am tents were being blown across the campsite with owners running after them
It was France for camping after that
