Not sure where to post. Admittedly a very boring question but I’ve got to drive from West Country to Gatwick south tonight to pick up relatives. I’ll leave 3 hours to get there i think. They get in at 9.30 pm. Will be coming straight back west. Am I crazy? Dreading the traffic, any guesses/experience of how bad it can be the last fri before Xmas and should I try to avoid m25 altogether?
