We drove to West Byfleet on Saturday - got a train to Farnborough Main. No parking problems and the nice man sold us a train ticket and a discount entry ticket at the same time! Leaving the show was just as hassle-free - didn't envy those in the enormous queue for the car park!
Show was OK - not the best I've ever been to but the MiG 29 was amazing (how does he do that
), as was the glider aerobatting on aerotow.
It's obviously a trade show primarily, but surely even the trade need the loo occasionally - not nearly enough 'facilities' given the amount of people there.
