But I do your quoted journey in reverse quite often and can be airborne 30 minutes after leaving the house. Sitting at 3000ft feeling relaxed, watching the traffic queues on the M40 or A34 knowing I'm not getting stressed sat in the traffic, means more to me than money can buy.
Spot on, Chilli Monster - I find long car journeys (or even short ones) quite stressful and tireing. A couple of years ago I had a job interview at BOH and decided to fly from Nottingham (thats EGBN not EGNX). The Warrior was already booked so I took the Tomahawk - even in the slightly slower PA38 the airborne time was a little over one and a quarter hours. I arrived feeling fresh having enjoyed the views on the way down. The interview done I had a spot of lunch and returned in the afternoon. The return journey by road would have left me wrung out and would have taken much longer and might even have involved a night stop - adding to the expense.
Even on the longer journeys I would take going by air in a light a/c every time over fighting it out with the traffic. Also it's much safer!
