------ My short list -----------
-Tuna Canyon -- a one way barrel of monkeys!
-Deer Creek / Sycamore Canyon road -- on a supermotard
-Glendora Mountain / Ridge roads
-Highway 243 from Banning to Idyllwild, then down the 74 to Indian Wells
-Highway 138 through Crestline, then down Rim of the World highway
-Avoid Angeles Crest Highway like the plague! Far too many stupid drivers and squids on sportbikes.
Pretty much any road near a national park in Utah
