I made this project that uses Instagram and a simple hashtag to try to make more bike parking in New York by getting the city to clean up abandoned bikes. Check it out here. deadpedalny.com
It's been getting some good press which hopefully will help it pick up momentum even faster there's an article on Fast Company. and another one on The Atlantic Cities, and one on Time Out New York.
Check it out, then take out your phone if you're in New York and help out.
