I've just started planning a road trip from dallas to san francisco with some two other friends. One of them is new to the US and I'm hoping to show him some of the gems along the way - Carlsbad Canyons, Santa Fe, Grand Canyon, Las Vegas, Death Valley, Yosemite, to name a few!
I want to spend 2-2.5 weeks on the road (driving an old sedan and leaving it with a friend in sf). It's probably impossible to hit all the above destinations on the trip... but are there any recommendations? Must see places, especially for that time of the year?
I've never done such a long trip before, so any comments from the seasoned folks here will be much appreciated. The critical constraint for the trip is the time (in september, about 2.5 weeks). So, if there are are alternate trips that will be better (from dallas), feel free to point them out.
