I'm not familiar with how theyset upshows where you live....but as far as I know in the US, if it is asingle show it will just say single open/single youth show and give thelocation. If there are more than that it will say doubleopen/double youth...and that stands for show A and show B...one rightafter the other, or sometimes they have a break or lunck in between.
In November we will be attending a triple show, but show C is the nightbefore, and the following morning show A will start at 8A.M.
I'm just not sure what your meaning by 3 or 4. Did you have a flyer with the information on it?
