Would these be size 500 mm Needles?

Thanks to the Champagne Bohemian for a great picture. Busy, Busy weekend. Hockey tournament for DN2. The first rink she played at was here. Yes, that is a Chinese Food Court/Plaza. The rink is in the lower level/basement of this plaza. It is one of the most disgusting rinks in the GTA. The bathrooms were so bad, one of the mother's came out and almost tossed her Timmy's, it was so disgusting. She was positively ashen when she came out. How sickening is that. Don't get me wrong here, I know some really horrific rinks. Double Rinks/Vaughan Iceplex is right up there as well. But loos that make you want to vomit? The things we do for our children. Gotta go make breakfast will try and update more soon.
