Has anyone, anywhere, ever seen a female garbage collector?

I, myself, have never seen a female garbage collector. I would like for someone who has, to let me know. I am curious as to why I have never seen one and, of course, I has me suspicions about the reason. It's a high paying job and it keeps you in shape, but it's stinky and nasty and difficult and I can only imagine the bullest of dykes wanting to do it, but then again, maybe not.
