I have spent some time researching around this amazing website and it has just left me even more confused then when I started. My friend and I are in our late 20's and want to see as much of the US as we possibly can in 2 weeks. I am thinking that we would be better off flying from NH (where we live) out to Vegas and then continuing to head west. We want to see the Grand Canyon, San Fran, wine country and possibly Seattle if there was enough time. Would people recommend us flying into Vegas and doing this, or driving from NH and trying to fit in as little as possible, while trying to see as much as possible? Any help you can give us would be great!
