Leopard gecko found near Main St, Watertown

I found a leopard gecko this afternoon around 3pm near the benches outside the Watertown Public Library on Main Street. It's about 4 inches long, tan with irregular dark brown spots and a slightly thicker tail. The left front toe has a tiny notch that makes it easy to spot. It seems calm and well cared for; I’ve kept it in a small plastic critter carrier with a warm pad and a little dish of water. If this belongs to you, reply here with the gecko’s approximate age and any distinguishing marks, and we can arrange a pickup in Watertown.
