I visited there a few times many years ago. They claim to be "America's first skating club". (Not if Canada is "American":
https://bootsandblades.ca/history/age-of-discovery mentions a club in Saint John, from 1833.)
They said they had a friendly ice dance group - they didn't only dance with their official partners and coaches, unlike most DC area ice dancers. A lot of figure skating sessions. The sessions I attended weren't busy - but that is a really long time ago.
They were a bit pricey, and by their current website, still are. Not a rink for poor people.
Current website still says "iPods, iPhones, headsets, walkmans, and external wireless/wired speakers are not allowed on any session." I wonder if they enforce that. I see them on the ice at virtually every rink I skate at. Odd that it says nothing about other types of phones and tablets.
Odd that a skating club merged with a "Humane Society". I don't remember any pets at the facility. Did you see any?
Close to the University of Delaware, with its own ice rinks (and a supposedly very good pro shop; many competitive figure skaters attend the University, and its staff has published articles about skating injuries and boots); and to a lot of other ice rinks - see my page. E.g., Ice Line and Iceworks both have 4 full size indoor ice surfaces, which making them ideal for figure skating competitions, but also for hockey (
). The University of Pennsylvania has its own rink.
Dr. Jonathon P. Contompasis is well known podiatrist who treats a lot of ice skaters around nearby Wilmington.
Also close to various dances associated with the Royal Country Dance Society, which I joined during college. And to Longwood Gardens, which is very impressive if you are into gardens. It is close to a number of small liberal arts colleges, including one I attended. And to Arden, Delaware, a beautiful but now quite pricey "single tax colony" founded by Georgian Socialists (socialism for the rich; it has a nice swimming pool at the Arden club, which is now a major social & folk dance center, and runs the annual "Arden Fair" with a flea market but also sells a lot of arts & crafts), where my mom partly grew up and loved. And to Hershey, Pennsylvania, where families go to learn about and sample chocolate. And to other interesting things.
