From the KCOI folks:
The Kansas City cyclocross season continues on Sunday, October 29 with the Boulevard Cup. The first race of the 2006 Maxxis Midwest Cyclocross Cup will be held at Wyandotte County Park, the venue for the 2007-2008 Cyclocross National Championships. Watch for more details on the race in the coming day, but if you'd like to pre-ride the championship quality course, your chance is this Sunday, October 22. Meet at the race venue, near Shelter A for 1:00pm start. Ride as long as you'd like; but leave some time for beverages and bench racing after. Email any questions to cross@kcbike.com.
If you want to travel a few hours this weekend: Nebraska Series or Tulsa
