So snow and ice is not a factor in turning out? We get plenty of both here, and snow packs to ice, I can't imagine what a pasture would have in it, be scared the horse would slip and break something, but that's just me, maybe they are more sure footed than what I think.
Maura, you are correct about the doable stuff, competing with commercial barns, well, there are none. None within probably 100 miles of me or farther. I have thought along those line of going small and moving up, but I come back to the same conclussion, build it right the first time. The indoor arena is mostly for me, it would be the only ridable place in the winter, that's 5-6 months a year here.
