So my mom and I want to put up a decent sized indoor on our property, the better to ride in the winter, and also to host dog agility shows and clinics. Anyway, wondering which companies you'd recommend. We just had a bid from a company for the material only (70x100) that was about $40000, but they have some delusion that I can put it up myself. I'm thinking that the building would end up costing about $150,000 installed, but I don't think that would include exciting things like stalls and electricity.
Anyway, we've looked at Morton and Coverall, the latter because it is so much cheaper. Worried slightly about winds though, as it gets pretty harsh up here (WI). Also, what size do you think is most comfortable? Ideally I want to fit in a dressage ring, so I'm thinking at least 70' by 200', but perhaps wider, ie 100x200', 220 including stalls.
