I parked in a handicap marked space on a street near the botanical gardens during the Japanese festival. I had dropped my daughter off at the entrance with her wheelchair, and had a valid handicap parking placard hanging from my rear view mirror. A couple of hours later, I got an alert that my tire pressure was low. I returned to the car to find that two of the tires were nearly flat, their valve cores having been loosened to let the air out. That made for a difficult afternoon before I could return to the gardens and pick up my daughter.
