Help Joe Miller
Hey, Joe! I didn't have much time to see the sights in the Western part of DRC other than the Congo River (awesome, by the way) but I can tell you that having some French skills will behoove you greatly. While you might come across some folks who still speak only tribal languages, in the city you'll have a pretty easy time communicating if you do so in French - even if it is only basic French. I encountered only a few people who (begrudgingly) spoke English there.
