If I have a little wiggle room in there, I would add RV to the list, which I guess then I’d say car. I am a full time RVer and the life of living on the road and traveling full time has so many benefits such as you approach every new area and space as a local as much as possible and see many unheard of places along the way that you would never otherwise think of, consider, or even know existed. We have stayed as honey bee farms, a lavender farm, goat farm and many other off the beaten path places around the country, and without the expense and f hotels along the way!
