The weirdness continues...

When I got home tonight, my bf wheeled my bike in for me and said, "You know, you have a flat." This was my other bike, not the one with the exploding tire from the OP. I had just ridden, and it was fine while I was out. I thought, that's funny, now I've had 2 rear wheel flats in the past 3 weeks. Then I remembered, last week my car also had a rear wheel flat. All the flats happened at home.

They say things happen in 3s.
