Vote a bike lane into existence
Build an app, that each time it's loaded, makes a note for wherever the app's user is. It's just a vote app. Load it, you voted. If the user wants, the user can also write a note about why a bike lane would be useful in that location.
This information is then published online. Every vote also automatically sends an email to the listed city representative (so we'd need a lat/long lookup table for the Denver Metro region, which correlates location to city representative), letting them know about it.
This is a great idea. Similar to crowdsource best routes for cyclists, maybe a complimentary app. Hope you or someone can come and pitch this idea at the event tomorrow.
