I guess I've got mixed reactions.
For my present career its great to fly in with loads of tarmac for parking and a feel of permanency about it.
However like John F, there is more than a tinge of sadness about it when I think back to my days in electronics, when I occasionally worked at Farnborough and there was lots of new equipment around and aircraft to see.
Many of the hangers that I either worked in or visited are now blocked off or just have "mundane" aircraft residing. However, I can recall with much fondness a week spent during the Airshow just being available there in case our equipment went wrong ( it didn't ) whilst the representatives of a certain country were there to view it with the intention of buying it ( they didn't !). There were suggestions that to avoid wasting my week I should do a bit of "stand manning" at the main exhibition site, but fortunately this did not materialise and so I spent the whole week loitering in and around the black hangar observing at close quarters the Red Arrows and the Comet Racer that were all parked in the vicinity.
Happy days!
