Thanks for the info Fred! That's kind of what I was afraid of. With the NPS and the SC State Park people not really having any info on the subject, I was pretty sure it was going to be gone. Back to the drawing board for our next daytrip I guess. We kind of like to theme them, and although it's not yet complete, I was looking for something to pair up with a visit to the Tuskegee Institute. Maybe now we'll take both days and head for Vicksburg. =)
Anyway, thank you again for the information.
Mark.
