I got the hot tub cleaned up in pretty good time right after work, and I'm satisfied with the results. I probably should've let the cleaner stuff dry (water was a little filmy when I started to fill), but whatever.
It felt good to do something a little physical, even if it was brief. I hate exercise for the sake of exercise, and I'm not sure I'll ever overcome that. But when I engage in physical activity for a purpose, that's cool.
Staying in the physical world, I tore down the remainder of the CoasterDynamix model that I built more than three years ago. With the new floorless train, I'm going to try and build a nifty compact model and take it to work. This kind of thing is also very satisfying because you're making something with your hands. I see why Tyler likes to build stuff out of wood, why Diana likes to knit, etc. There's something very real about making stuff with your hands.
