You didn’t even clearly explain where you’re going from and to.
What route do you wasn’t advice on
.
From Gardnerville?
Gardnerville to South Lake Tahoe?
To Florida?
Explain better.
Are you from the area? Or from far away?
My first bit if advice is you don’t want to go through either of the mountain passes you mention.
My concern is only from Gardnerville, NV to Las Vegas, NV. No, I’m not from the area. Yes, far away. It’s difficult to plan a route that does not include mountain passes.
