While kayaking a nearby lake last Sunday, I noticed about 50-60 people on the sandy beach, and I marveled at the noise they were making. Looking at this photo I don't feel so bad about that group now...and glad I don't live in Miami, Florida.
If you've ever wanted to make a difference but found it hard to believe that one person could... check out the Kiva Team Caedes discussion thread and discover that anything is possible.
