If any of you are planning on taking Hwy 491 (previously 666) from Shiprock to Monticello Utah, be advised that the road from Shiprock to Cortez is in really bad shape, full of lots of nasty dippy-doos. You'll probably notice the black brake streaks on many of the dips. It's driveable but when you hit that first bump, slow down because they just keep going on and on. Felt like our toad was going to come unhitched when we hit the first one !
