From ***Daves blog. This was done in three long trips many years ago. Driving a load of portable toilets to Phoenix & hauling back sodium nitrate to Utica, MI (about 35 years ago). A meandering round trip to Hendersonville, NC in 1976 in an old Champion motor home, which I let my oldest son drive through West Virginia before I realized it was all downhill going South. And I didn’t know the brakes were crapping out! The last was a flying trip to FL for my mother’s hip replacement surgery. I flew to Orlando & then drove to Zephyr Hills. I found driving through miles of orange grove at 3AM in the summer can be nauseous from the citrus oil.
