I think I might be lucky enough to spend a month in Wellington this coming winter. I’ll be trailering my own horse down, and have the option of either doing it as a 2 day trip with a layover, with me as the sole driver, or making it all in one go (about 16 hours) with a second driver along for the ride. I think there are costs and benefits to both, but would be curious about how others feel. My horse is good on the trailer and hasn’t had loading issues while I’ve had her, but I’ve never made a drive longer than 5 hours with her.
Bonus for recommendations on a good (or warnings about a bad) place to stop overnight near the SC/GA line.
