Sooooo, here are your clues...
We'll be driving through three states total, (which includes our own.)
We will be staying by the coast (and I mean, seriously, within 1/4 block of the coastline!)
It will take us two days, or about 16 hours total, to reach our destination. (We have the amazing opportunity to stay in an incredible lake house for one night on the way)
We'll be within rock-throwing distance of a hyper-saline bay. There are only a few in the world.
