Anybody in PA have tips for Herping this region?

[melissaisdown]

Hello all, I'm new here, and new to herping and I'm just wondering if anybody from this area (Southwestern PA) and if you had any advice on the types of places to go in search of things. The trail I run on has given me a garter, a water snake and of course toads but I'm hoping to find something different like a Queen snake. I know they eat crawfish mostly but I know no place in my county where crawfish abound. Thanks in advance.
