Did I mention that I've recently moved to Longmont, CO (near Boulder)? Anyway, I was getting frustrated that I couldn't find any online bike maps that cover Longmont. I quickly found the official City of Longmont Maps page — although they talk about bike maps, none are available online from the city website.
Updated Aug 12: In the comments, Pete points to BicycleLongmont.org which contains a 2008 front (pdf) side of the map. You'll still need to use the Wayback Machine for the cached back-side (see below) which includes helpful info, like which parks have drinking fountains and restrooms.
Thanks to the Wayback Machine, I found a Feb 2007 cached version of the City of Longmont page, which had links for bike maps as of 2006. Even better, the Wayback Machine actually cached both these PDFs:
City of Longmont Bicycle Map 2006, front (pdf) and back (pdf)
As for other Boulder-area bike maps, the ones I like the best are the 2006 Highway 36 West corridor map (pdf), from the Bicycle or Walk section at 36commutingSolutions.org site, and the maps at the City of Boulder's bike section.
Head over to http://www.bicyclelongmont.org/ for a 2008 Longmont bike map.
Jeff,
You'll have to see about doing the bike trail down pikes peak too. It was way cool!
