At the risk of being a party pooper here, let's try to veer back to the OP's subject.
You had to say pooper didn't you! Just when I wanted to show everyone my spot.
Think of a place where I might have a spot that is not well lit usually.
Don't worry, when you get old enough someone will come along and light it up for you.
But seriously folks (return to topic), I have yet to find any water or other mystery fluids under my C14. Dog pee
on the back wheel once, but that's it.
