Thanks again guys. I'll need to crunch the numbers and see how it all works out mileage and time wise. I'm not massively fussed about Reno, to be honest, this trip is all about the scenery for me I think. I know it's a case of 'how long is a piece of string' but any idea how long I would need to allow to do a circuit of Lake Tahoe? Maybe I could have a bit of a lazy day on the Monday and do that then head east afterwards.

I'm still undecided about the route after Yosemite and will need to ponder on this. Has anyone drive US-199? I have heard that it's a place that can't be missed. But then so is US-1 so the opportunity to drive some more of the beautiful coast is swaying me... Decisive, me? Hell yeah! :)
