heres my lay out, and have you ever considered leasing a property?
the house I bought 4 years ago has four acres unfortunatly they are not all adjoining because of a road that runs through the middle. However I did fence the portion behind my house and have a small one stall tack shed back there. The tack shed part is 14 by 10 and the stall is 14 by 12. Its handy for when I want a horse closer to home, but I lucked out last summer and found a farm that I could lease.the people leased me three pastured fields of there farm for 150 a month and I have use of two barns and a shed row int he deal. I know most farmers arent willing to do that but you could talk them into it by suggesting you rotate your horses with their cattle. Good cattle farmers rotate their herd from one pasture to the second pasture every few months and if you remind them that horses do not carry the same species of worms as cattle and that by rotating the horses on the "off" field they would actually eliminate the worms contaminating the grass. Anyway , I just thought I would throw the idea out there for your considderation.
