My son played in a national baseball tournament in Vincennes a few years ago. I wondered why they would hold the tournament in Vincennes, but figured it out once we got there. The field was only average, but they turned out a bunch of really nice people to volunteer and make the tournament great for the kids. Everywhere we went there were nice folks. I have no idea if any of them were Mo, but I doubt it - I have pretty good Modar. Of course the 90+ temperatures and 90+ humidity may have thrown me off my game.
A cool old downtown on the river, some interesting history, and even has a college. But the town seemed to be struggling economically.
My favorite thing about Vincennes: the high school is the home of the "Alices". Yup, the team name is the Alices. You have to have a bad-ass football or baseball team to go out on the field as the Alices.
Its a good 2 hour drive between the two. Carmel is the snobby well to do suburb (thus the future Indpls temple) north of Indianapolis. Vincennes is a rather remote southwestern Indiana town north of Evansville.
There is an LDS ward or branch there but this is the midwest - most people in Vincennes probably don't even know its there.
Toyota has a large manufacturing facility in nearby Princeton.
If you like small midwesterny towns, Vincennes fits the bill.
