Yup... I forgot about the tolls... that's something I've not had to deal with (short of the one on US 19 before you get on 77/64...)... I've never done the drive between Pipestem and Charleston... Been through (well, around) Pipestem numerous times while heading south to the beach/etc... I did have a stream-design class down there at the resort, that was a nice stay (short of the straight-from-the-70s hotel rooms), I did get some golfing in...
anyhow, best of luck with the results... crossing my fingers for a good report back in the next few days
