I-64, Exit 195 (south), Laburnum Avenue, the Cracker Barrel is a 1/4 mile on the left and a great landmark as a thought. From there, it is about a 20 minute drive to the car show.
Between an 8:15 & 8:30 departure from CB would be suggested.
Reminder, please let "Old SGM" know you are inbound to reserve a smart spot. I could arrive at CB around 7:30 for breakfast and to open the window for early arrivals.
