Map challenged...

I have decided that I am an idiot...I was in Yosemite on Friday afternoon and after taking some pictures headed to Utah. I looked at the map and saw that Highway 120 looked very windy and 395 to Carson City looked really small. I then looked at 120 to Modesto and for some idiotic reason decided it would be faster to drive halfway across the state of California in a Westerly direction so I could hook up with I99 and go up to I 80...It ended up taking an extra 3-4 hours than if we had just driven the small highways up to Carson City and to I-80...I'm not sure why I thought that would be faster, or even a good idea.
