Anyone who remembers the Doune Classic Show near Stirling, around 2001 - wettest, coldest weekend I ever spent in a tent. The first afternoon - Friday - some guy in a Stag towed a caravan up the sloping campsite and spun his wheels the entire way leaving two huge trenches across the field, and after that every other car that followed just made them deeper and muddier. Everytime we went to the stalls or beertent we had to do the WW1 'over the top', and climb out of one trench, cross no mans land in between, drop into the other, clamber out covered in mud, and do the same on the way back. People were falling into them in the dark. I had to buy a new pair of shoes in the village for the trip home.
