I did participate in a USFS workshop with Tanith & Ben in 2006 in Michigan soon after they won their Olympic silver. The ice was broken up into sections for beginner (including me), intermediate, and advanced skaters.
We'd expect nothing less of them as they always exemplify the finest sportsmanship, but yes, they were very encouraging and positive, and offered lots of great tips. They also demonstrated their original dance from that year and gave a lot of insight into the technical requirements involved.
Parker Pennington, and Tommy Steenberg was my coach for a few summers.
Well, I once almost took out Ron Kravette on an early-morning session (fortunately he saw me coming before I realized he was there and he has good ice-dancer reflexes and stopped me without taking us both down!)
Often saw Justin Pekarek on the same sessions. (And his now-mother-in-law once helped me out of a tight spot with a dress problem--hooray for people with sewing machines and sergers! Especially nice of her as her daughter basically volunteered her help, THEN asked her!)
Otherwise, skating, no, but got to watch a lot of awesome people (probably most affecting was watching Oleg and Ludmilla Protopopov practicing one day.)
I skated with Tai Babilonia and Randy Gardiner in Santa Monica in the '70's.
