On the way in, I left the house at 6:00am (I live about 2hours away from the airshow) and drove straight in, there was about 5mins traffic.
On the way out, it took me 2 Hours just to get out of the base, in total it was 5 hours to get home for an hour and 50min drive.
My friend drove up in a motorbike and said he was driving past about 14miles of traffic.
I blame the roads for being too small (not designed to cope with the traffic) and Leuchars for making us drive around the whole base when we could have just drove straight out.
