I think I actually know the location of that particular barn. I was just there 2 weekends ago.
Initially, I thought it was wierd, but let me tell you that at least in their set-up, it was really convenient. The stalls are very roomy, and have a same-size outside area for the horses, so it doesn't make the stall seem small at all. Actually, it makes good use of the normally dead space in the corner. The inside section is set up with the waterer in another corner and feed bin in the third. The door latches and there is room for your own personal lock.
As for not wanting to be in the stall tacking up with the horse, they had several cross-ties, outside hitching rails, and of course you could tie the horse in the stall, or outside in the (very) wide aisle. Overall, I thought it was awesome, and I wish I could afford to keep Mick there!!
