^^^ know what, not really a comment on that stuff or whatever, but I skated on my first NEW ice last weekend. They dump everything and do a new sheet every Summer and the guy I do a private drop in with, opened the ice for our drop in....it was so odd during the warm up..... Looked like you were 1/4" above the surface. First time I'd ever done that. I was late the next day(would have been the 2nd skate on the ice), so didn't see if it changed much. Anyway...just worth a mention. Sorry for your delay. Say "they", guess my home ice. I have 6 sheets(5 rinks) within 15-20 minutes. But AFAIK, they all do this.
