Today I walked down the tracks and over to the Marigold shopping center, a walk of a bit over 15 minutes. I brought a folding shopping cart with me.
The walk there went well, but by the time I was heading back my knee was bothering me quite a bit. What would have made a difference would have been a place to sit. There is a rock I can sit on close to the center but later, when I'm near the tracks, nothing.
I will feel like I have come quite a way when I can make this walk regularly without pain.
