Okay, it's an estimate, but it's kinda interesting...

It looks like we're coming up on 300,000,000.
If each one of those 300,000,000 would give just 50 cents to the Reds, we could be rooting for the biggest payroll in baseball. I'd give my four bits, and I suspect there are a couple of hundred of you that would do the same. Then we'd just have to work on those other 299,999,800.
