We can now say we have driven all of Interstate 10 and seen both coasts. Our RVing thus far has brought us from Texas to California then up to Oregon and Washington, through Idaho to Utah, back through Texas again, and we have now reached the Atlantic Ocean. Here are two comparison photos of when we hit the Pacific versus the Atlantic.
This coast is SO much warmer and the RV spots are dirt and grass instead of the concrete parking lots we found in California. We're loving Florida!
