It's a bunch of farmland in the middle of Indiana. It's so rural and country here that there are a number of topics here on RF, such as restaurants and fashion labels, that I'm utterly clueless about because they don't exist here. There is such a lack of things around here that often I have to drive 60 miles north or south to Indianapolis or Fort Wayne for something that isn't around here. Want a cake for a wedding? One town 10 miles north has one such bakery, a town 20 miles south of that has two. Music stores? We don't have options. Electronics stores? Few and far between. About the only things you can "shop around" here with are bars and churches, as those are the only things plentiful enough that if one tells you no you aren't left wondering were to go next.
I know nothing about Indiana...for some reason, when I opened the link you posted, it took me to southern Utah, with an emphasis on Cedar Breaks National Monument right around Cedar City.
Now I MIGHT have put it down to, well....I was just there and the thing could have been a reflection of my Google maps search before I went on my trip, except....I didn't do a Google map search before I went. In fact, I had no idea I was going to BE in Cedar City and environs then; I had been headed to Fort Bragg to see the glass beaches there.
...........but there are these fires up around Yosemite and such, so....
So that wasn't it. I wonder what happened?
ANYway, you are describing a typical rural area, where, if one wishes to have a wedding, one generally bakes one's own cake.
I did mine, after all. Decorated it myself, too, AND I made my own dress. (shrug) Or rather, I made my cake and my sister made my dress. Looked darned good, too. The cake tasted wonderful, as well.
I don't suppose a gay couple would have any more trouble doing this than I did...or that straight couples would have in the same situation, where there's only one baker in a territory that big.
