What about layovers?
When we have an overnight layover the horses simply stay in their trailer stalls. We settle them in with their dinner and we give each of them 5 to 10 gallons of water right there on the trailer. The trailer stalls run between 8 and 12 feet long and in many instances the horses are even able to lie down.
Being able to stop for the night gives the horses a chance to relax and refresh and take a break from the road before continuing on their journey.
We generally stay in well lit hotel parking lots. My personal preference is the Hilton brand as they have big turnaround areas and comfortable places for the horses to have a quiet night. (ie: no loud truck stops). I always get rooms where I can see the trailer at all times throughout the night. The trailer is always locked and properly secured. There are off site layover areas across the country but unless a horse is one that needs to come off for some reason, and is also a fantastic loader, then it is always less stressful on the horse to simply stay in his trailer stall where he feels safe and secure.
We are happy to disclose the layover details when en route if you have any questions.
