I now know what Stevie Wonder did after he retired from singing; got a job as Traffic Manager at the Great North Showground!
It's a magnificent site with oodles of parking areas all beautifully laid out and maintained so it should be easy to ensure a rapid ingress of multiple traffic streams and avoid queuing. All it needed was a couple of marshals splitting the traffic off the tarmac drive into four or five streams and directing them to separate parking areas. But no, we fill one car park at a time, one vehicle at a time and let the traffic back up all through Harrogate and the surrounding district.

Mind you as a veteran of many Game Fairs I've seen even worse; he gets around that Stevie.
I bought a milling slide vice in as new condition from the Myford stand, a few chunks of steel plate and ally for (yet another) project, and tried to buy some carbide tool holders and tips but the chap couldn't take a credit card. There being no cash machines on site I'll order them off the internet. As a one time aero modeller I really admired some of the 'planes on show especially those still being worked on.
I'd go again but not make it a day trip from Mid Wales; too much driving. We hired a really lovely cottage about five miles away just recently, so I'd build the show into the programme and let The Management trawl the shoe shops in Harrogate for the day.
My super duper highly intelligent on-board computer and SatNav detected the queues on the 62 and took me an alternative route .... the one used by about 100,00 other vehicles all presumably equipped with the same bit of kit! Nightmare.
Phil, my bad.
