neighbourliness or service interventions

Courtesy of Kottke’s Quick Links, I am pouring over this list of one hundred and one small civil- and civic-engineering hacks that one could apply to any community to improve it. Just a few select ideas that could be pitched to municipal-councils or could shame city governments into action:

66. Turn snow piles into sidewalk ice bars
79. Host a movie out-of-doors
98. Map your public produce—stray fruits and vegetables that go unharvested
13. Guerrilla gardening revolution
71. Become a tour guide and showcase your neighbourhood

What do you think? Was there one idea (or a hatful) that resonated with you that you will try? Surely all of us can try a little urban exploration, at minimum.
