If he was on 75 South, he could have been coming from 74 or 275. I'm not from the area, but I'm down there a lot, so I'm trying to remember where that exit is in relation to other things - he could be coming from Colerain, perhaps - he could have taken Cross County over to 75. Colerain isn't a bad part of town, really, but I do know drugs can be common in some parts. Or maybe from some part of 275. Hard to say - on maps it looks further away, but everything in the Cincinnati area is pretty close. He could even have been coming from West Chester - hard to say, other than a party, what would have him out there at that time.
