a few days ago i was trying to come up with reasons to give my employer to offer incentives for folk who ride into work. i started scanning the web and i came across this. http://www.bv.com.au/file/file/RTW/BICY%20-%20Cycle-Fndly%20Workplaces_v12.pdf
it's basically a presentation on bike commuting benefits, for employee, and employer. it outlines necessities, accommodations, and rewards really well. Since i shared this with everyone at work, 3 other people have joined in on riding to work. now a coworker and i meet up three times a week to ride in together.
