A very reliable source ( member of Rhett's family) has shared that she received a call informing her that Waterfire, an established art ritual in Providence will be dedicating one of its lightings to Rhett.
Waterfire is a Spectacle which draws locals, natives, and tourists.
Here's the site: http://www.waterfire.org/
September 27 is the date. I did not see it on the schedule, but I may have missed it.
I never heard Rhett comment on Waterfire, although I may have heard him comment on fire water given his scholarship on Native Communities...
