A belated "thank you" to everyone who replied, as I was on a glorious vacation visiting DD in NYC.
Some odds and ends, addressing various issues that popped up:
I will have a couple of years to scope out retirement places while my DW is still working at our current location. We also aim to take some long vacations as test runs.
I'm fairly confident that my lifelong interests will remain intact through retirement, though I find it fascinating that others haven't found that to be true. There have been some changes (e.g., I no longer sing publicly, but still attend concerts) but the core interest remains.
It seems like that stretch from Tennessee through NC and western Virginia might be tough to beat. Rare combination of mountain trout fishing and warm water lakes. Maybe not the last word in arts stuff but enough at a local university to keep me going.
I had frankly forgotten about the trout fishing in Sacramento.
As far as fishing goes; I'm a minimalist - no boat, just waders and a rod.
