(Tigard, OR)  --  Police are reporting no injuries after a large tree fell on and crushed five cars in a Tigard neighborhood.  Officials say high winds caused the oak tree to topple early yesterday morning onto the vehicles, which were parked at homes on Pine Street.  Crews needed about eight hours to clear the street.  Washington County crews have had to deal this week with a number of other fallen-tree-related incidents caused by weather.
