Aloha All, My wife and I are one week from our first trip. Northern Colorado to Santa Fe. A bit longer trip than we wanted but my fault due to poor planning as we are trying to keep to no more than 3...
My list evolves as I travel. We realized we needed something and went to Walmart and picked it up. Eventually I've gotten to the point where I need to go through and lighten the load.
My best advice would be to make a list of things you HAVE to have and are difficult to get on the road, like prescription meds. Make sure you have those things and take a little extra cash for the other stuff.
