Yeah, good ol' eastern fence lizard, Sceloporus undulatus; one of the most common lizards in the Ohio Valley, Mid-Atlantic, and Southeast. They make decent pets. The males like to do 'pushups' to display their iridescent blue ventral patches. They're 'looking only' lizards, though, not 'handling' lizards.
Like everyone else said, please never release pets again. It is very irresponsible.
