There used to be one in Atlantic City, but people preferred a warmer climate. I think there is one in western PA, also called tri-state (PA, Ohio, WV).
@Jim Pemberton may have more information on that program.
Old days there were more than a dozen trade shows, all small , all regional. Then they combined into one. Then more folks found out there was money in holding trade shows and things began to splinter again. But not to the extent it once was. Glad I don't have to travel to 12 or 15 locations each year.
Pick a trade show in a location you want to visit and combine it with a vacation. Not enough cleaners take vacation. You need some time to unwind and get refocused on the long-term of the business rather than just working on the day to day.
