Wow, I have lived here in Montana for 33 years and I have never heard of Ingomar. Don't let the article fool you. There are probably at least 100-200 other similar bars for around the same price in towns which are relatively close to the same size.
I grew up in North Dakota, this bar sounds like a lot of small town bars I grew up around. I'm sure you're right on them being a dime a dozen, our "local" aka 20 minute drive away bar had unpaved roads and also yes did have spots for the horses.
