This is the best volunteer organization you will ever participate in. First of all, it is huge and has projects of all types, all the time. Second of all, if you don't want commitment, you don't have to commit! Just call in a week or so before you want to volunteer. So on busy weeks there are no worries, but other weeks you can jump right in. Lots of fun things to do with kids, seniors, building houses, cleaning parks, etc.
