Got an early start... then foiled again

I left the truck stop around 5 AM local time and made an uneventful trip in to Fairfield, CA to the Busch plant. Dropped my trailer, got weighed, found the preloaded trailer I was to pick up and hooked to it. Unfortunately, during my pre-trip inspection I noticed that one of the tires was flat, with zero air pressure. None of the three or four tire locations in this area opens before 8 AM local so I get to wait for a few hours to get one of them out here to fix the flat. The load is maximum weight so I won't even attempt to drag the trailer to them.
