Ben,
The current sequences are available on the IMAC site:
www.mini-iac.com
Next year's sequences are in developement- if you join IMAC, you can see the proposals and comment. If not, you'll have to wait until they are finalized.
There were two IMAC contests within an hour and a half of your location:
Parker, CO: Crosswinds contest
Littleton, CO: JEFCO contest
Mike Hurley is in Colorado. He writes the Scale Aerobatics column in Model Aviation. He is a great resource. Check the IMAC site under SW region, contest results for listings of contests held this year. The contest CD's are another great resource.
