When you’re Under the Big Tent, it’s all about having fun.

Even outside the tent — at the seafood truck, for example, or the rock-climbing wall — there’s fun to be had, too.

Saturday marked the fourth annual Under the Big Ten party outside of the First Baptist Church in Bay Shore — a day of free food, activities and entertainment.

The day is run jointly by Great South Bay YMCA and First Baptist Church volunteers.
