US 41/I-70 in Terre Haute is a nightmare. Plan ahead and leave early to get in/out of the fairgrounds. It's all screwed up, can't turn left here, three down to two lanes there etc. It's bad now, wait til the event. Here's a article in the paper about it: http://www.tribstar.com/local/x864259533/Expect-a-big-traffic-backup?utm_medium=facebook&utm_source=twitterfeed
