Stuck in Erie

So my parents wanted to goto Toronto this weekend and visit some friends. Either way we were just out side Erie and then the temperature shot through the roof and we pulled over and realized something was wrong with the radiator cause it was cool to the touch and after thousand some miles of driving I should have been hot enough to cook on. Well we called a friend and he decided we probably had a sticky thermostat which would explain the fluid not getting in the block and therefore not cooling in the radiator which would in turn make the radiator hot. Sigh... So no we are stuck at a AAA workshop trying to get this radiator thermostat installed.
