I believe Harding trained at a mall rink in Portland for a while?
(Not the best example, but it's off the top of my head.)
I would think it would be difficult to train and run programs with the public looking on.
I believe she trained in Clackamas Town Center mall, which is where the shootings occurred a couple years back. There used to be an ice rink there, which has since closed. (I remember this because my son was in that area of Oregon when the shootings occurred, so I was following the news closely, and Tonya was mentioned on the coverage.
