Painting Ice: How do they do that???

Ever wonder how an ice rink surface is painted?  All those lines, circles, face-off dots, team logos, advertisements, rink names, etc., etc.  Most people think the paint is applied to dry concrete and then the rink is flooded and ice is built up.  Not quite.  Watch this video first (for some reason it won't download from youtube properly, so click the underlined link).  It best explains the process.  Then watch the time lapse videos of crews painting the ice below.  They will give you an appreciation of the work that goes on before your blades touch the ice.  I hope to get over to my rink in June when they start the painting process to see it first hand.
