After texting you about the frog: A bit of history first. February in 2003 was bitter cold. I was helping to side a house in Cambridge, MD. A fountain was frozen solid, but I could make out a shadowy movement. Breaking the ice I found this frog. Fully seven inches nose to vent. So cold, no perception. I arranged him and shot from about 16" with a point and shoot. Put back in fountain. It refroze in a few hours. No digital data so a picture of a picture. Surprise, your frogs look alike. Not native to Md. Either. More tadpoles bought. Probably wild caught, they are heard to ID at that stage. Bull frogs have become problems where they have been introduced. Is this one next?
