In my trailer, bound for Saugerties: my big green upright trunk (since I don't have a tack stall for just the one horse), complete with grooming stuff, bathing stuff, tack cleaning stuff. Fly sheet, scrim sheet, stable sheet (54* nights! woohoo!). Hay, grain, shavings. Wheelbarrow, fork, step stool, braiding stuff. A little cooler filled with sandwiches, homemade watermelon applesauce (amazing!), water.
In Amy's trailer, bound for Morven: standing saddle racks, bridle hooks. Grooming, bathing, tack cleaning. Sheets. Table, chairs, tack room banners. Hay, grain, shavings, etc.
