I've driven to cp from hazleton,pa twice last year and it took me almost six hours exactly. Traffic shouldn't be a problem on 80 day or night because there aren't too many cities along the way. I would probably prefer to make that run during the day because the drive from cleveland to the eastern part of pa is boring as hell. The only thing is that driving in pa sucks cuz there is construction everywhere. You might want to check out the status of it at
