Community Service

One of the things that I'd like us to do more of in the future is community service, giving back to our community in some way.  Our class has been blessed with having the support from a lot of people, either through our fundraisers or through the work that we do with our videos.  We are fortunate to receive the support we get each year, and I think it would be a good idea for us to do more for our community.  I'm looking for something to do say once a quarter that our whole class could participate in.  What I'd like to hear from you is:  
1) What do you think about this idea?  Good?  Bad?  Do we have enough time?
2) What are some ideas that you have that we could do as a class?  Some examples could be to start a food drive, collect cans and donate the money to charity, pick up trash along the road, participating in some sort of fundraiser like a walk to end muscular dystrophy or something like that.  
3) How often should we do this?  Once a month?  Once a quarter?  Remember that whatever we decide, we need to commit to.

I'm challenging you to think outside the box here.  Be creative and use your imagination.  Any idea will be looked at so don't be afraid!
