Yeah I'm terrified of heights, even getting on a folding ladder makes me nauseous and shaky. We went to this place in PA that has a bridge with a glass floor - Kinzua sky walk. I was there for my friends mothers funeral and they dragged me out on this thing. I cried. Actually, that whole thing was weird, I grew up with my friend, her mother passed from cancer and they had the funeral up in PA. I drove 5 hours down from NY or so to go...which turned from a funeral, to a hike over that bridge (in full funeral attire), to a BBQ.
DH isn't afraid of heights, we don't have a ladder tall enough to get up there (and I'd suggest at least a harness!) but he's away at school for a month and won't be back until October. It's a tin barn with a tin roof, I know those are slick. My parents have one, but it's not nearly as tall, you could easily pull a semi through this barn.
I don't mind patching, even though we are renting. If it was mine I'd probably have the whole roof redone. Of course, I'd put stalls and a tack room in there instead of equipment though. It has a tack room but it's not accessible. My landlord lives next door and is using half the barn for storing some stuff. I didn't really "need" the whole thing, but I would have liked it.
Mini, I do still have the dog. Nobody has claimed her, or even called to see if she was theirs. No dogs like her reported missing or anything.
