Wasn't there a post exactly like this about a month ago?
Longmont is an interesting choice.... It's not exactly cheap. And there isn't anything of note there other than being a suburb of Boulder that farther from Denver. Oh, and it's on the way to RMNP. Other than having lots of sidewalks and bike trails (pretty typical in the front range anyway), it's just another pre-HOA suburb town. Strip malls, developments, nothing special. If you chose Longmont based off the blog, I'd do some more digging around for alternate locales.
