I am relatively new to roadtrips. I have done one roadtrip in the southwest from Austin, TX to San Francisco, CA. I am planning another roadtrip with a friend, late in the summer, maybe in the last week of August or second week of September. This one will be from Austin, TX to Miami, FL and we are planning for about 5 to 7 days. If anyone has any suggestions about must-see places to see along the way, places that need to be avoided etc, please share.
