Two Skies...thanks for the update! It makes planning much easier for us...we are coming over US40 from Denver...was wondering about some of the good riding roads along that route...oh well, maybe next time!
This one's a bit out of the way, but if you took I-70, and are looking for a scenic road with some twisties, you could incorporate it into your trip to Tooele:

You could detour from US40 across 191 from Duchesne, but that'd easily add a couple of hours to your ride.
Members from our group ran the loop yesterday. The road itself is cleared, with some wet spots from snow melt.
