Vrai hit one one aspect of it - opening a store with no local market. You don't open a sushi bar in a town that thrives on ribs, steak and barbecue. If you have a niche market, it better suit the area. As far as I can tell, there ain't no shortage of bars or bait and tackle places, and those usually aren't franchises. It amuses me that you can open a bar next to ANOTHER bar, which is next to a liquor store, and both do well.
I was disappointed that this area lost at least two Indian cuisine restaurants, but I can understand why - they can't compete with more popular steak, seafood and Mexican food. You may WANT to open a hobby shop because it interests YOU, but if the local population isn't into skiing or kayaking, you're not going to do very well.
The kind of stuff I've seen go up reminds me of Ned Flander's "Leftorium" - his store for left-handed people. Quaint, amusing, but you're not going to go there and buy anything.
Which by the way, segues into something I've said this area could use, for years. An indoor shopping mall. There's no place to put it, really, and the anchor stores would likely have too much competition because the population isn't there. But an indoor mall has one thing about it - it allows for the support of unique niche type stores. Even simple ones, like candy stores. You won't DRIVE to a candy store (unless it's, like, Lindt's) but you WILL drop in and buy something if you're in a mall. I mean, let's face it, would you make an intentional trip to go to an Orange Julius, or Mrs. Field's? Malls allow tiny stores to thrive, even if they just sell sunglasses.
