Hi Rooftop Gardeners, I’ll be talking about my new book, “Roof Explorer’s Guide: 101 New York City Rooftops,” showing slides and sharing some insider’s tips on roof exploring at the Mid-Manhattan Branch of the NY Public Library. After the talk, we’ll celebrate with specially crafted and deeply discounted “Roof Explorer” cocktails at the fabulous rooftop bar, Bookmarks Lounge, on the 14th Floor of the Library Hotel, just a few minutes walk from the “real” library where I’ll be speaking. The talk is free and not too long! The cocktails are only $10! This has got to be the best way to spend your day after Labor Day Tuesday evening. Hope to see you and your friends there.
