Well, I dont know about the feedlot issue, but that isnt quite the whole story in Lincoln.
A track was proposed, there was a primary name, with silent, racing, but non-drag racing backers. Those in the area will figure that one out.
They were willing to go the extra mile with financing, but the original proposer could never come up with the funds to acquire the land, and tried to buy some key (read Expensive) sites. They sold the idea without having key pieces of the plan in place.
Scribner was for sale, but its location has always been an issue, Omaha has Glenwood, (1/8mile) where short sightedness prevailed, and Lincoln seemed like an ideal location.
But word around O is that land was never seriously negotiated for, and the break even based on car count would limit what would ever get built.
Dont shoot the messenger, that is what I heard from some Omaha based racers this summer that had driven back from KCIR.
