Thank god you didn't do it at Harwarden - You get 3 points for each offence up to 9 points!
You'll probably get shot at!
Im sure they would rather keep your buisness - Your next visits landing fee will be a similar amount.
The airfield have a difficult job though as its the threat of the CAA that makes them take this sort of action.
Try Sywell though - One of 2 airfields I know with a bit of common sense (you dont have to wear them!)
