I would think they would have been transferred to Yukon because I have not seen them on the X10 or X14. Probably some of the stickers have not yet changed.
From my knowledge and sightings and as other members have said, these are the local bus transfers to Charleston: 6191, 6193-6197, 6199-6208, 6210-6230, 6232-6236, 6241-6244, 6248, 6252-6253, 6258, 6261, 6271-6277.
