Well that sucks for us. I hope he has a happy retirement, but he and the rest of the Pickers are pretty much irreplaceable.
SDC already feels different since Cedric/Cajun Connection left, even though they were never really part of the whole 1880's Missouri theme, lol. You can't just lose a long time piece of the culture like that and expect it to be the same. Not sure what the park can do about it, but I hope they seek out other performers to take up residence.
