The campsite is quite safe I beleive, wouldn't give too much chance of anywhere being safe, Jez. Our car got done outside Ma in laws place on one of the quietest streets in Selby. Last week we parked it for a weekend while we cycled and camped for two nights-not touched at all- in a lay by !. So you take your chances-there are quiet streets about 5 mins walk away from town-I live on one, might get a space on one of those.
See ya laterEric
