We stayed here so that I could have a flying lesson in a Tiger Moth at Duxford & we could use the buses into Cambridge - great location. The serious incidents we experienced have already been mentioned by another visitor to the site - "troublesome teenagers throwing stones over the fences and trees". On the first occasion fortunately we were not on site but our motorhome was damaged and the pitch littered with rocks. The perimeter fencing next to our pitch (43) had been breached and there was a well used path. The club management took no immediate action to protect us but they were very sympathetic! The following day we remained on site and "they" came back to have another go - I went into the trees and prevented this from happening - we could have ended up with serious head injuries had I not done so. There appeared to be a lot of talking going on with the regional manager but no action was taken to prevent entry to the site. As a 70 year old (with a new hip this year) I had to remove the debris from our motorhome roof and clean it followed by tidying up the pitch (we were told to leave it "as is") and it was me who contacted the police to report the incidents. Subsequent complaints to the club have been very poorly handled (insulting really) and we have not had a response regarding the safety and security (and risk assessment) policies and procedures that are in place. Not having had a satisfactory response I will be applying for compensation via the small claims court. Ruined holiday and very stressful, not to mention having the motorhome off the road whilst we are arranging for repairs to be carried out.
