I attended the last 2 (& only) USAC races at Lincoln.
In 2010, I was stunned at how well the locals did.
Mackison 4th, Monteith 5th, Bitner 11th & won the semi (with 360 motor ?), & Marks 16th.
They seemed to really take it seriously & invested the time & resources to do well.
It caused quite a bit of positive buzz within the Posse fanbase, who seemed to really appreciate the differences.

In 2011, the locals crashed, broke, or didn't do well.
Wonder if that's why Lincoln didn't bring 'em back ?
Too bad. It was great while it lasted.

Here's #21 Monteith in his 2010 heat race.
