Hey everyone, i am new here

Me and a friend just dicided to take a road trip from the east coast to the west coast. I plan to start going me research very soon, since i want to be prepared. I have a million questions that i am sure have been answered, so i'll be searching these forums a lot.

But, i would like to ask one right of the bat

Is 3 weeks a good amount of time for us? We would like to be lazy in California for a few days, and don't want to spend all the time driving. I want to do the trip justice. I really have no idea what i want to see on the way either.

Thanks in advance, i look forward to picking your brains over the next few months.
