Eighty-six years is a long time to do anything. But that’s how many years the Ossining Historical Society Museum has held its annual Gala Dinner. The OHSM’s 86th Annual Anniversary Dinner and Silent Auction will take place on October 20, 2017, at The Briarcliff Manor. This is our big fundraiser for the year, the one that supports our programming. It’s always a fun event, and there are plenty of high-end antiques and objects to covet and bid on. The $85 ticket price includes dinner and open bar for wine and beer. Sip and bid: It’s a win-win! (The more you sip, the more you win.) Reserve your spot by October 13 by calling the Museum at 914-941-0001.
