Lost 150-foot string of colorful festive lights with a waterproof timer box near the picnic area at the park during a holiday event.

I accidentally left my 150-foot string of colorful festive lights at the park during the annual holiday event in Fredericksburg. They are a mix of red, green, blue, and white bulbs, and I think I might have left them near the picnic area while we were packing up. They have a small waterproof box with a timer that allows them to light up at night.
