From where we live in Hampshire to where we wanted to go in Suffolk for the weekend was 170 miles. It took six hours to drive it - that's a magnificent average of less than thirty miles per hour, which is probably only slightly faster than a horsey could do it, provided the horsey wasn't stuck in the traffic on the M25 like we were.
In order to bypass the traffic jam we were stuck in we cunningly took a short cut through even more traffic in Enfield, during which we firstly got rear-ended by an idiot in a car behind us in the traffic queue, and then witnessed a full-on house fire attended by seventeen million fire engines, thirty five billion police cars and an ambulance, which helped alleviate the boredom of sitting there not moving.
