Me and my gf are planning a trip across the US this spring. Because of work obligations, we could just be away for three weeks.
We will arrive in San Francisco the 30th of March, and return from Miami the 21st of April.
Depending on the route we will choose, this will be at least 6000 km (3700 miles), which rougly translates into 300 km (185 miles) per day. This is of course quite a lot of driving, but should be doable in not much more than three hours per day. And in areas with not so much we want to see or visit, I can imagine we can drive 10 hours in one day, and as such "save" a day.
This will be my 7th visit to the US, but my gf's first. I would like suggestion for routes and/or things we "must" see. Initially I was thinking to go from SF to LA along Highway 1. Then Las Vegas, and the shortes route across untill New Orleans (or maybe Houston). But I've now started to think that it will be too much desert, and maybe it's better to head up for Utah, Colorado and Rocky Mountains... It's a far bit longer, but I guess it will be more exciting also.
The route should not be planned too precisely beforehand, we want to be able to improvise a bit during the trip, but the big picture would be nice to have planned before.
We know that the time is way too short for a proper road trip, but it's what we were able to now. We are not really restrained by a budget, so anything goes.
Please, any advice would be appreciated.
