Blue Hydro Flask found near downtown library

I found a blue Hydro Flask 21 oz this afternoon around 2:15pm outside the downtown Gainesville Public Library on Main Street. It has a small dent near the base and a faded sticker with a lighthouse graphic. The lid screws on tight, and there’s a faint scratch along the rim. On the cap someone etched the initials 'LK'—could be a helpful clue. If this belongs to you, I'd like to get it back; I know it's important, and we can arrange a meetup near the library.
