This was once the location of the old Bonne Terre Zephyr Station. When it was opened, the owners were told that it wouldn't last 2 years, that "people will never pump their own gas and buy chicken." Now, some 40 years later, the name has changed, but business is good.
You are looking for a small magnetic keyholder. Wheelchair accesible although might be hard to reach.
Thank you to B.J. and Chuck for permission to place this cache!
