So we don't have a January 2018 trip planned yet, but I want to put February on the calendar. I'm thinking for Feb, we'll make a trip to White Wash Sand Dunes, outside of Green River. It's a neat, open-travel play area with sand dunes, slickrock and neat, tight canyons. I'm thinking late Feb, so it'll be a little warmer but the sand should still be wet and easier to drive for 4x4's. There aren't dunes nearly as big as Little Sahara, but still plenty of bowls to climb and play on. Those that want to camp, could... or stay at a hotel in GR.
That sounds like a good trip. Hope to make it
