Successful outing accomplished. I just have to take my time and rest during the activity.
I got to the Laundromat and read while the sheets washed. I put them into the dryer, walked to the uptown 104 bus stop, sat there and read until the bus showed up, rode it four blocks to the bank, and there my left leg decided it had had enough. I managed to cross to the middle of Broadway where I sat on a park bench until the light changed, then got to the downtown 104 bus stop. Once I got back to 82nd Street, I sat on a bench in the middle of Broadway, between the uptown and downtown lanes, and read for a while. Then, I was back to the laundromat to wait till the laundry had dried, and I am home.
Unfortunately, this won't work if it's something that needs to be accomplished quickly. I have no idea how I'll cope with that!
