Yeah, if the gasses didn't mix, we'd all be dead.

Carl, I totally agree about post transfer purging being more important if you didn't start with a closed transfer.
Personally, I closed transfer except the receiving keg has the purge open, but exiting co2 should prevent the vast majority of o2 from entering.
Now I'm kind of thinking about giving the filled keg a purge or two just to make sure it's all co2 and no o2 snuck in.
Necro, what Carl said. The whole co2 blanket thing is basically a myth. I think someone on milkthefunk did the math and found that the 'blanket' is diffused in about 5 seconds.

I'd be willing to bet you're safe with the purge being open, but it's so easy to do, it can't hurt. I'm going to clean up the spreadsheet I just made with purge calculations, I can send it out or post some info if people are actually interested.

Necro: I see what you're saying, and I'll say a couple of things in response. First off, on seeing CO2. CO2 is a colorless gas. My suspicion is that you keep your CO2 in your keezer. So you have cold CO2, which gets colder when you break down the pressure across the regulator (most gases auto-refrigerate when you decrease their pressure. CO2 in your tank is at something like 600 psig, so it will actually cool quite substantially). So now you have very cold CO2, mixing in a keg that was probably just rinsed with hot water. When this happens, you'll condense water vapor in the air, forming a bit of a cloud. At least thats my guess.
