Same thing as going up, let the drivetrain do the work, shift into 4 low if you have to.
The only thing I would add is just because you can, doesn't mean you should. Ice house isn't a bad road, but with it being 1 lane in either direction, it really sucks having someone either going up or down that has to go really slow, backing up traffic (depending on the crowds of course).
If you're ok being "that guy" you should be fine. I'm not saying right or wrong, one way or the other, just another thing to consider.
