While riding the motorbike to Alabama to see the Barber Museum (way cool!), I rode up to Anniston to see Tom Morris.....his house and shop are amazing.
He built the house 25 years ago, and added the new shop when the other, very generous, shop was outgrown. I imagine that the has about 50 airplanes underway, as well as stations to assemble and package his various widgets...
Tom reported that he spends about 70 hours weekly in the shop!
It's amazing!
