As a newbie to Scottsdale, a free trolley ride seemed like a no-brainer for acquainting myself with the area better.
The driver (Barb) was a great gal with a friendly and happy disposition, who all too happily answered all of my newbie queries, and even gave me a lot of useful tips for getting around the greater Scottsdale/Tempe area with minimum cost and confusion. She was professional, courteous, knowledgeable, friendly, and an excellent ambassador for Scottsdale (though apparently she lives in Tempe and not Scottsdale).
One of the passengers who boarded while I was on my full-loop ride seemed either intoxicated or simply 'messed up' and fell off his seat twice. Barb handled the situation very tactfully and with his best interest and safety in mind, though he was somewhat belligerent and resistant to her help. She handled it really well, I thought.
I love that Scottsdale has this transportation option and think they've done a good job laying out the routes and timing. And I love that the buses look like trolleys! Fun stuff.
