This is a fantastic thread. I've enjoyed reading each post.
I volunteered for this event: did four six hour shifts noon to 6 pm, two at the official hotel Marriott Copley, two at the TD Garden for Information/Transportation. SO many sightings of my favorite skaters from all over the world - Rika, Sotoko, Yuzaru, Boyang (he's tiny!), Javier, Patrick, Grant, Alayne, many others I recognized but couldn't name - but no other contact - volunteers were not allowed to approach, speak to skaters (idea being that they should feel safe/comfortable and we were there to assure their ease). That said, there were one or two memorable moments for me...
1). Max Aaron is SO handsome! Much more in person than on TV... A real presence. Black hair, dark eyes and ruddy hi color complexion.. He caught my eye and nodded with a small smile as he passed my table in the hotel alcove.
2). Watched Ashley practice about noon the day of ladies free skate .. Emotional. Gracie was skating too in full costume and looked beautiful
3). Madison & Evan came thru the revolving door headed for the escalator at the hotel. He was looking in the opposite direction but she glanced over at me and I smiled at her like this

she gave me an even bigger smile ... Gorgeous!!!
4). Finally a rather funny moment at the TD Garden... We were all handing out starting order sheets as fast as we could... A big burly guy size of a football player came up to me.. He had dark curly hair and was wearing a headband with Winnie-the-Pooh ears. As I handed him his sheet I said, "You wouldn't be a Yuzaru Hanyu fan by any chance?" Without skipping a beat he said: "Drat!!! And I thought I was incognito!!"
Last, but not least, I had the pleasure of meeting Coyote Chris of GS fame at the TD Garden... It was wonderful to see him!!
This was a fun and thoroughly memorable experience.
