Prior to retirement, I spent most of my career in the wholesale hardware and building material business. District Mgr. with Do-it-Best (old HWI) and Ace Hardware and attended National Shows across the States. Manufacturers are the majority of the booths, but major wholesalers also attend with their booths as well.(Here in the US) Show attendee's at the ME shows are probably construction companies looking for product sources. There also may be some retailers from the region attending, but don't know how the mix would be there. Perhaps someone else on the board would know more about attendance.
