Some actually do pick up trash along the highway. Other options include donating time to an animal shelter, march of dimes, doing meals on wheels, donating blood etc. (First BB test, I built a web site for a local non profit.)When I think of community service the first thing that comes to mind is seeing those guys in orange vests along the side of the freeway picking up trash.
Could you give examples of the types of community service the hopefuls at your dojo have done?
