Lynn dropped off a knee scooter and a walker to me to borrow. I haven’t tried the walker yet, but the knee scooter is great — it let me easily bring in the box of plants that had arrived on the porch (some jasmine from Jed) and unpack them. Baskets good! Hands free to do stuff also good!
I’m going to try to keep practicing with all the mobility aids, as I suspect they use different muscles and being comfortable with all of them will be the optimal strategy for maximizing capability. But grateful for generous friends!
