I didn't realize it until I got to the park, and decided to try walking around a bit anyway. It was immediately obvious that I wasn't going to enjoy it, because it was mowing day, and there were giant riding mowers everywhere I went. It'd be bad enough walking around trying to dodge those dudes and feel like they're watching, but having to listen, too? Pass.
The day wasn't a complete wash. I came back home and did some exercises using a home gym that came yesterday. It's the kind that's rubber tubing, handles, straps, and door anchors. Today I did three rounds of all the exercises that use the door anchor in the high position, at the lowest weight. Whee.
I'll probably go back to the park tomorrow. Assuming mowing only takes one day.
