Hopefully it's not too late to register (I already have) but if you haven't already, you should get your tickets to the Museum of Ice Cream opening later this month in the Meatpacking District. The pop-up location will be at 100 Gansevoort Street from July 29th to August 31st. As you can imagine, lots of ice cream and lots of info about ice cream.
The opening day, July 29th, will be free for anybody willing to do first-come-first-serve. But after that, you gotta purchase tickets. Just $30 for two. Do it!
