The fill sand/clay mixture that was spread in front of the garage doors made a nice driving surface as long as it was frozen, but was very messy when thawed, so another solution was needed. I spread the white rock on top of landscape fabric in hopes that the rock won't be swallowed by the mud underneath so easily, and only ordered enough rock to cover the approach to the door where the car is parked. The picture above is a couple hours into the second afternoon when I had my routine well memorized and a misty rain kept things moist.
Here's the view from the house roof the next day showing the extent of my progress until I ran out of fabric. I intentionally wanted to save a bit of the rock in case I need to make the layer of rock thicker anywhere, so I think this configuration should be good for at least a few days.
