I still live in Ardmore and take 177 frequently. Just watch out for the town of Asher and Dickson. Their cops will nail you for speeding.
Back when I worked for OSU, there were times I preferred 177 to 35. The very first time I drove one of a university vehicle (a black Impala), I was afraid I was going to get a speeding ticket because I didn't slow down fast enough. The town I was driving through had the declining speed limit signs from 65 to 35 or 25, but it was all downhill, so I hadn't quite hit the lower limit when I reached the sign - there was a cop facing the road, and then another in the parking lot that pulled out behind me. Thankfully, there was a semi behind me, so the cop nabbed someone coming the other way instead of me.
Needless to say, on every subsequent trip, I slowed down well before the sign.
