Every six weeks we spend a week in Brighton. It's about 270 miles via M1, M25 and M23, not a bad run but I hate the M25.......who doesn't? So the other day I found out that weekends and at night London congestion charges don't apply and that both our cars are exempt from emission charge. In the old days , pre M25 I used to enjoy driving through London , Sundays at the right time were usually fairly quiet. So on Sunday we are going to give it a try, at a guess it's also about thirty miles shorter, quite honestly it's worth trying. Of course this could all be avoided if somebody requires a couple to house sit a Brighton property on a permanent basis.
