Funny. Last night I had a dream not unlike my old elevator dreams.
I was going to visit my brother-in-law Jharod at a military base. Part of the visit included travelling on a trolley or train-like platform on rails, but it didn't have rails and in fact there were openings in the platform above the wheels.
Later in the visit we had to ride an elevator, but one that didn't travel just up and down, perhaps like the transport tubes in Star Trek? This one, however, had issues. The doors didn't close so we got to travel up and over while being exposed to the dangers of the open spaces and machinery.
