This class I've always done in a near by nature center.  It's always fun to take a group out scavenging and see what they came back with.  It would be fun to see what a group comes back with after a personal scavenging and perhaps, if there are any people who are close together, they could meet for a scavenging adventure.  Go out and scavenge before we meet for this class.  We'll share stories and adventures.
