most curious indeed, looks like a heavy duty race type awning workshop nailed into tarmac but with no branding or livery, the yellow Cortina and car in front looks to be parked at top of a fair slope that drops to an area with a tall security prison type fence that looks same height as windows of 2nd/top floor of building behind, no idea where those 2 racers/riders can be going, no other fans milling around, the 3 Hondas look too clean for post race, no ideas at mo and am trying to think of anywhere you'd find the 3 Honda bikes parked up like that with only Dunlop tape for security.
