oh my this was definitely not a sub-5 image. I thought it was a great message for this challenge. Also the wording on the bus really pops out too. Not sure why the voters could not show this a little more love.
It kinda sorta meets the challenge, but I'm afraid it doesn't go beyond that to meet any sort of aesthetic qualities necessary for a photo competition.
the fact that cities are doing this is a great sign - it is a bit of a 'scavenger hunt' entry rather than an image that would draw me in for a photography challenge - but it clearly meets challenge
