There is nothing much left, in a tangible sense, of the interior of The Frontier. There are still some sections of outer wall which remain up, (as a shield between pedestrian traffic and the demolition work occurring on the other side of the wall), but it is nothing more than an empty face; like the bank building at Rhyolite.
Photographing the north entrance, I saw something interesting in the rubble. A traditional rotary wall phone, with a sign above it: EXECUTIVE OFFICE.
I love traditional rotary phones, but I'm nostalgic. It is amazing to me that on The Strip, this phone with sign, lasted to 2007.
