I used to have various deals from lubricants and fuels development to them as well as energy, maintenance and environmental (land remediation especially) with them.
was - am out of it now....the interesting part to see were the racing teams (like surgery facilities) and some of the truck plants (for pure scale - and sometimes how backward they were, like Peterbilt in S.Carolina, talk about piecemeal and custom....).
Back in 2005, my friend and i spent a fortnight up in N Yorkshire, visiting a different racecourse every day. Well, we did 10 courses in those 14 days, visiting York on the days when there was no racing near by. And when i say York, i actually mean the King's Arms on the banks of the Ouze. Would love to repeat that experience but the racing fixtures have never since provided the opportunity.
