To directly answer your question, no.
However, it IS on my bucket list to make it to the festival. I've been to Barber twice to see the museum and saying it is incredible is the understatement of the century. I was thinking I'd make the festival this year, but work obligations made it impossible. I want to go back this fall, but might wait until their expansion is complete and go next summer or fall.
There is a Simplex in the museum, by the way.
Anyone going, take pictures!
