In the info pack it says about camping in "tents, caravans, motor homes" ... I'll be showing up (if it makes it) in a ratty, rusty old transit van (just like the good old days of DC Racing but this one is grey) ... please let them know it's a racer not one of our beloved traveling friends
TBH £5 for decent toilet and washing facilities isn't bad at all, been to many a camp site charging more and offering less!
