Thinking 'bout milestones

Here I am pushing seventy, playing guitar for more than fifty, and always boasted that I never took a guitar lesson or even made a conscious effort to learn a new chord, never played slide, used an open tuning or stepped on a wah-wah pedal. But for the last couple of weeks, I've been using the internet to learn a couple of jazz tunes (Round Midnight, Everything Happens to Me) and last week when Harry Manx came by with his new 6-string banjo, I became enamoured with the DADFAD tuning. Wonders never cease.
