Composting Experiment - Update

So as I'm sure everyone else is experiencing, we've had an unnaturally cold winter this year, which took a dip south on the temperature gauge shortly after the beginning of my experiment.....

I'll admit that I haven't done much with my compost since I posted the beginning on Jan 7th. I have rotated the standing one every time I've added to it, but I'm ashamed to report that I've only braved the cold about once a week to add to it, only to find after the second week of additions that the whole thing had frozen solid!
As far as progress goes, you can't see much out there. The freestanding composter has finally thawed out, so I'm trying to mix the contents every other day. But other than that there's really nothing happening in any of the three locations.
Here's hoping the weather warms up soon as we start making some progress! I CAN'T WAIT FOR SPRING!
