I have a small bucket just for fence repair. It has hammer nails sharpie and tape measure. No need to hunt the items when I need to take something up. Also I can carry it on the mower and tack up a loose board as I go along.
Love
my dump cart from TS. Use it for everything.
I hve pass throughs in the fence line- just left out the center board of the three board fence. Easy.
Clothes line in wash stall for hanging towels rags leg wraps even wet saddle pads.
Plastic caninets from Sterlite(?) in wash rack for all bottles etc. I have short ones that provide a countertop and a tall one.
When you desogn the barn be sure you have a space space for hanging forks etc.
