In our shade structure, we had a leather-bound journal where we invited Challenge participants to leave us a few words about how much they had enjoyed the experience. There are a lot of curse words and very descriptive suggestions to let us know they love us.
By the end of the week, the journal contained pages and pages of guest messages and art. I believe one of the post-Burn projects is to get all of the pages scanned and posted as a slide show, but meanwhile I took snapshots of just a couple of pages.
