Changing a flat tire

Last night after going for a walk to check the skies for northern lights, which was a failure due to clouds and rain. I decided I needed to return a library DVD. Taking the usual route I only got two blocks away and was preparing for a left turn. In the dark and rain I misjudged when the turn lane was coming up. Plowed up and over a curb, flattening the tire and denting the rim.  Luckily I waited until morning to change the tire and put on the donut. It required lots of kneeling and half turns on the two-handed crank which I managed to do by kneeling on the crank and pulling up with my good hand. That took 20 minutes. By that time my left leg was completely shaking. One handed lifting of a tire requires a knee to get it into the back of the hatchback. The new rim won't be available until Tues. and will cost $160.
