I don't have boaders, just my own and a couple training horses in at a time. The stall barn has 10 - 12 x 12 stalls, small bay for tractor & equipment,small bay for hay storage (The bulk is in our hay barn, try to keep 25 bales or less in the barn...i have a major fear of barn fire) & tack room & wash rack. I use the wash rack a lot! I will take some pics when I'm out there later. When my gpa built it he had big metal piping put in the concrete and made a stock of sorts in the wash rack. It gets used for much more than bathing. It's wonderful for the vet to palpate & ultrasound mares, address wounds in a very easy to clean area, soak sore legs, and I always do sheath cleaning in there - if they think about kicking I can get out of the way safely. Our indoor is attached to the stall barn and we have 2 - 12 x 24 foaling stalls in the front corners. Lots/Pasture - I have a large outdoor/also serves as pony turn out for my daughter's pony who gets fat looking at grass. We have 2 large pastures we rotate for the herd, 1 gets used for mares & foals part of the year and 3 stud pastures. We have good ol' red brand horse fence around all of it with 1 strand of barb, the stud lots have 2 strands of tape hot wire at the top instead of barb.
We have about 17ish acres of woods behind our pastures & barns that I ride in...haven't had to make any trails myself as the horses & deer have carved their own through the years. I would strongly suggest you convince the hubby to let you make trails, it's where I find my sanity and it's a great break from the monotony of daily arena riding for horse & rider :)
Life is like a camera. Focus on what's important, Capture the good times, Develop from the negatives and if things don't work out, Take another shot.
