It's been a few years since this sign first went up. Claudette and I always take a look at our surroundings when we are out walking but we've never seen anything...
I was walking through the park at the end of the block. I crossed the rusty bridge over the creek from the park on the way to McD's for lunch. As I was walking the path along the top of creek bank out to the main road, I saw a mountian lion meandering in the creek bed about 20ft below.
I watched it walk away around the next bend in the creek while silently cussing myself for not having a camera.
