My subject line could be off a bit, but I think I'm close.
Richmond 1.0 - the rough and tumble, pockmarked pre-Paul Sawyer track
Richmond 2.0 - the half-mile dirt surface from the late 50s through the late 60s
Richmond 3.0 - the half-mile asphalt bullring from the late 60s through February 1988
Richmond 4.0 - the three-quarter mile asphalt wonder that hosted its first Cup race on September 11, 1988. Davey Allison in the Harry Ranier #28 Havoline Ford won the pole and the race. Click article for larger image and better resolution.
