My initial thoughts as well. But then I remembered that the Harrisburg show would always fall on the same March weekend as the huge MACA show. What I would do was drive up I83 to Harrisburg and do that show in the morning. Then back down I83 to the MACA show in the afternoon as it is right on my way home to Catonsville. Did make for a looooong day and sore feet! Could do the same substituting York for Harrisburg. But do have to agree that one show would help cannibalize vendors from the other to a degree (how much is questionable).
