Hi Lisa,
We only use C.C sites and the only one I have been ill at ease in was Clumber Park,They have special frames on each pitch to enable people to clamp there bykes to , but some still get stolen along with other items.I kept a close watch on on all our outside equipment untill the weekenders had gone( Not wishing to slate everybody)but i read on this forum some time ago that a member had had some of his outside stuff stolen by weekenders.
If I had to carry locks and chains to attatch the outside (ie water bottles and waste master) I would give up Caravanning.
