Today is the Seventeenth day of Tammuz, the start of a three week period that ends with the Ninth day of Av (this year, on July 22-23). During this period Jews worldwide lament the destruction of the Holy Temples in Jerusalem so many years ago.
Here's a nostalgic video made up of postcards showing the facades of many of the older Catskills hotels, some of which you may remember visiting, or at least seeing the directional signs posted at highway exits. The music in the background is the Yiddish song Vus is geven, is geven, un nit do (What was, was, and can never be again.)
