I-68 (National Freeway)

[skluth]

For a naïve traveler, who doesn't, well I just pray there isn't an accident caused by the trickery.

Huh?
What kind of accident would there be???   Someone without a GPS/Atlas/Any kind of pre-trip planning sees the "Ohio and West" sign, takes I-68 - and when it ends at I-79 and they're not in Ohio (or west), they decide to come to a complete stop in the middle of the interstate out of frustration causing rear-end accidents?  That sounds ridiculous.
Or, when I-68 ends - not in Ohio- they don't know what to do and end up so lost, and refusing to find somewhere for bathroom breaks, end up having an "accident"??

While the the navigation value of the sign is up for discussion, I feel pretty confident it won't directly lead to any accidents (certainly nothing worthy of prayer).

Someone much smarter than me once said something to the effect "Never underestimate the stupidity of the American public." I'd like to think Mark Twain, but it was more likely PT Barnum.

If Pennsylvania wanted to be dicks, they'd put something on I-95 southbound saying 'alternate route to Baltimore: take US 322 west to US 1 south'.

Not that Chester Co really needs the help.
