Saturday’s 38th Annual Country Auction was full of good deals, friendly competition, and plenty of fun. The Historical Society of Greater Port Jefferson is so very grateful for everyone who made this event possible:

❤️ the community members who consigned and donated so many items, without which we would not be able to have an auction;

🧡 Wendy Walsh, our favorite auctioneer;

💛 our volunteers, whose many hands made light work;

💚 the buyers, who made the Country Auction so much fun!

Thank you so much for helping keep the history of Port Jeff alive. There are so many people, and each of them, from the cooks who fill our café, to the company that puts up the tents, are the reason this event works.

It was great to see you at the 38th Annual Country Auction. Let’s look forward to 39.
