I Passed My Test!!!!! Today the Zoobie Brush Mobile successfully passed the California State Smog test. If it hadn't it could have meant retirement for the prehistoric little truck, but since it did pass, it's good for at least another couple years. I bought it used for $1000 sometime in the 1990's of the last century, and it has born up remarkably well all this time. The people who owned it before me all must have taken very good care of it.
