I live near Exit 176.. It is Roll the dice... you can grap 476s before scranton.. then work back to 81 after wb... going to suck up time regardless,,,
I have gone way out of my way twice because of traffic / detours,,
cortland ny area down to Rt 15,, all the way towards harrisburg.
The other time was 15s 99 70 to 81,, was maybe 30 min differnce,, but i got lucky
