I've also seen him when I mow the lawn. The other night he was stuck to the outside of my kitchen window.
But the funniest thing was when - one night my daughter opened her window to look outside. (we don't have screens) - next thing she is running screaming. I finally figured out she was saying a frog jumped on her.
It was then up to me to capture him - while he was jumping around her room. And then put him back outside. This guy sure gets around!
