Dumb DUmb DUMb DUMB Tour Schedule!

The tour dates for Black Label Society / Corrosion of Conformity / Eyehategod / Red Fang make no sense! After going east to Sauget, IL (D) , they then backtrack to Omaha, NE (E) before going back east to Chicago, IL (F). Someone needs a geography lesson....
Here is a text version of the tour dates:

1. 12/27 Denver, CO @ Ogden Theatre
2. 12/29 Sioux City, IA @ Anthem at Hard Rock Hotel &Casino
3. 12/30 Kansas City, MO @ Uptown Theater
