The outdoor rinks in NYC are gearing up for the season and the very first to open is Rockefeller Center Skating Rink on Saturday, October 12! I walked by the rink this morning and gone are the cafe tables and chairs -- yipee! In its place, however, was a gigantic lattice-like plastic covering over the rink (see below). Is the rink going green I wondered? Then a worker explained that the plastic is filled with something like antifreeze and when it gets cold enough, the color changes from white to green. And that is how they are prepping the rink before actual ice is introduced. How fascinating! Click here to see the 2013-2014 Rockefeller Rink hours and prices.
