you have no idea...
Before I continue the Artscape trip report, just wanted to mention that my car is fine. One of the exhaust pipes had rusted through, that's why it was so noisy. It was a bit expensive -- I guess it must have been a big pipe! But anyway, at least it's fixed and it was nice to see my mechanics, who I really like. They wanted to hear about the parades, and I told them about the sunflower car in Houston, which really impressed them. The funny thing is that now my car is so quiet, when it's idling I can't even tell it's on! The car must have been getting gradually louder as the pipe rusted out for a while now.
