While waiting for the general session to start, the lady behind him was telling her co-worker that she had missed the shuttle and the people mover wasn't working yet, so she had to walk in the cold.
Not being afraid to ask or talk to strangers (my friends know this about me), I turned around and asked what the people mover was. I was envisioning a flat sidewalk that you stepped on and it moved you to where you needed to be (like in the airports). This would have been perfect for me since I am currently in a boot for tendonitis from running.
She explained it was a vehicle that stopped at different places (similar to a subway) and immediately our walking expedition last night popped into my head. I had seen an elevated track above us as we walked and I finally put two and two together. The tram is the people mover. The lightbulb literally turned on in my mind.
Never be afraid to ask questions!!!
