"How To Use MyBikelane
Bring your digital camera or camera phone on your next bike ride.
If you see a car/truck/etc. parked in the bikelane, take a picture of that car, making sure to try to capture the license plates in your picture (if they are not clear, that is ok, we will still take the pic).
Upload your picture to our site (using the button in the upper right) and tell us where you saw this incident.
Browse around and see other submissions.
if you have questions, find bugs, have feature suggestions, or just want to say hi, feel free to contact us by emailing us at firstname.lastname@example.org."
