I live an hour from the Rubicon trail. I am also in Florida, i won't be back in time. However i have driven I 80 end to end. I just drove I 44 to get to the east coast this time. I 80 is a much nicer drive. The dessert is warmer than usual right now. Needles ca was 119 when i went through. Defiantly test your cooling system. More stuff to see between the Rockies and sirra nevadas on I 44, longer drive it seemed like and hot as heck.

I 80 to auburn turn left on highway 49 follow signs to Goerge town, more signs get you there. End up in lake Tahoe. Heads up when i left a week and a half ago gas in auburn was 2.95 a gallon more in the valley
