Lost large red and white striped beach umbrella with tilt feature and carrying sleeve near the lake at Chautauqua.

I lost my red and white striped beach umbrella on Saturday while I was at Chautauqua. I had set it up next to the lake, and I must have left it when we went to lunch. It's a large umbrella with a tilt feature and has a carrying sleeve attached. I really hope someone finds it because it was a gift from my parents!
