Great thread! Here's mine for yesterday.
Best: On vacation and staying at a lakeside resort, got a really good deal on an upgrade to a nicer cabin, with a hot tub!
Worst: I have a kink in my back between my shoulder blades.
Interesting: We took the round-about scenic route to get here, which took us thru several very small towns that look like they haven't changed since the 60s. It was like traveling thru time.
