I just saw this posted to twitter today- the CDOT Bike Program is doing their first bike count this year at the end of March. They are looking for anyone to come out for a two-hour stint Tuesday March 27th, 7-9am, or 4-6pm, and Saturday March 31st noon-2pm.
I volunteered last fall and it was pretty easy and fun.
Here's the contact info:
