I just found this legislative alert and it may be of interest:
The bill will be heard on Thursday, May 5, at 2:00 p.m. in HCR 0112, in the basement of the State Capitol. An announcement will be printed in the House Calendar, which can be found at this site: http://www.leg.state.co.us/ (click on the "Calendar" link under the heading "HOUSE - Current Regular Session").
The maps and reports in this packet will also be posted online at: www.colorado.gov/Redistricting. Click on "Proposed Congressional Maps," which is a link in the "Quick Links" column on the right.
