3.2 oz = 40:1
2.4 oz = 50:1

Yonsracing,

America's really into sex, aren't we? The avatar isn't exactly the most appropriate, especially when we have users viewing threads with wives, children, parents, and so forth. It's not really my decision to make you change it, but keep in mind that some may not appreciate it for the reason that others nearby may get the wrong impression.

Nice find, by the way. Sure looks real.
