Dear Kim, Susan and Cathy,
I just wrote a letter addressing this same issue to Susan Stinson. This
letter may provide some useful information for you as well. I think this
focus of study(trees) is a good common denomenator for students. I've
also thought that this is a focus that leads into awareness, community
interaction, intervention, social restoration and provides a solid
platform for building on bigger issues.
Good Luck! Let me know how this works out and what focuses you've taken
with the artists you chose to highlight.
