If you are going to be around Torrey/Route 12 again, don't miss this side track off Rte 12 ...
incredible road, mostly gravel. Most of it is wide single lane, except for the bridge which is narrow single lane but paved ... DON'T LOOK DOWN! :)
and just outside of Boulder is Burr Trail ... awesome piece of road
I love Utah, can't wait to get back there again.
