Thanks for starting early. I was going to be too busy tomorrow to post anything.
It is July 4th, 1976, and while many folks are honoring America's 200th birthday by having family backyard BBQs and waiting for the evening's fireworks, there are tens of thousands of folks working this day, whether soldiers guarding our freedom, doctors and nurses tending to burned fingers from those fireworks, service industry folks keeping us housed in hotels and fed, truckers moving perishable goods, and railroads keeping shipments moving.
On this day a photographer caught a Conrail GP-38 moving some freight cars to the classification yard. She had not seen this many cars painted to celebrate the bicentennial at one time before.
