We're supporting the development of an Earn-A-Bike style program at a homeless shelter where we helped build out a small bike shop.  We're borrowing heavily from youth EAB curricula and models, but trying to account for the special needs of a different population (who might already have bikes, and who may need to fix theirs tonight so they can get to work or wherever in the morning).  We're going back and forth on how to support people through a useful learning and earning process while accommodating people who just need a quick wrenching.  We might have EAB night and open shop night, where open shop night can be accessed after you complete the EAB curriculum.

Suggestions are welcome, and we'll be sure to post materials to the wiki.
