Living in Florida, and very near the water, we bug-in. We've got food, fuel, generator, water, etc. However, in the event of some other event - like a nuke in Miami, we would haul what we could and relocate, likely staying with family for a while.
We are, however, in the process of buying a little something in a state that enjoys all four seasons, and is pro-RKBA, as a future investment/vacation home and possible bug-out location if necessary.
