This is a stretch for being considered "Regional," but I thought everyone here would like to see this. I recently had the opportunity to participate in creating the best website about Denver's existing and expanding light rail system:
http://www.transitdenver.com. The website is created by frequent Skyscraperpage "Interior West" forumers who had nothing better to do over summer than take many photos of light rail. I am responsible for probably about 25% of the photos and most of the "Statistics" page.
The website was created primarily to support the upcoming FasTracks vote this November:
http://www.rtd-denver.com/fastracks/index.html. As part of the FasTracks plan, my consulting firm is in charge of the US 36 Denver-Boulder corridor:
http://www.us36eis.com, which is what I work on 90% of the time.
Hope you enjoy the site and the many photos!
