Small cars will get you 40 mpg and can carry a load in the dry. I love bikes intensely but they are impractical for carrying large loads. We are set to bug in but have a virtual "home" in containers set to throw onto a truck and into the camper. The camper is not fancy but dry and comfortable. We have places to go so we will NOT be refugees which ever direction we decide to go--or have to. Our home will be where ever we stop as we will be ready for an indefinite stay where ever it is.
