I like tin tops best. With holes cut in the roof and pop tops attached. It says "motor caravan" on my log book. Oh yes and I like looking at splits. Preferably from the outside.
It does pose the question to be fair "why don't police park up outside pubs on a weekend and breathalyse all drivers leaving the car park"? I've often wondered this.
Very few do in town centres. I wonder if you would get planning permision for an out of town pub without a car park!
