Charity work

Caltech is organizing a "make a difference day." One of the opportunities is:

Join our team to work in the outdoors planting
trees in urban areas in order to enhance green
space in the city environment. Project sites
include North East Trees and the city of San
Marino. Expected project duration: 5 - 8 hours.

This amuses me because San Marino can certainly afford to pay people to plant their trees. As the Los Angeles Times says, "Money and San Marino are practically synonymous." Sure, civic involvement benefits communities from tent cities to palaces. Nevertheless, I think I'd be more likely to choose a different option.
