Authorities say 464 motorists have reported damage from last week’s 40-mile driveway-sealant spill on the Pennsylvania Turnpike. A leaking valve on a tanker spread the gooey substance over the eastbound lanes of the turnpike in western Pennsylvania. The Pittsburgh Tribune-Review (http://bit.ly/s9Sotm ) reports Tuesday that the number of damaged cars may be even higher, since some complaints may have gone directly to insurance companies. Authorities are still investigating.
