I rode over to the airport good and early, and took the plane out until it got too bumpy, then stopped and looked at Chris' PC on the way home - I left him installing Windows again.
After I'd been home for a while, I was going out on my bicycle ride, and decided to ride over to Stephan's and pick up the van. So, 25 miles and 2 hours later, I got to sit in traffic on the way home.
We went out and rented "Guardians of the Galaxy: Volume 2", and I noticed something on the floor under the van - one of the new rear brake cylinders seems to be leaking. Joy.
