On the Mack and Special Transport Day, companies that specialize in exceptional transport, such as low-loaders, present themselves. In addition, collectors show their old American trucks. And finally crane companies come with their heavy equipment. In recent years, the day was organized at Borchland in Amsterdam-Duivendrecht. But housing has to be built there too, so organizer Willem Kuiper had to look for a new location again. The Abcoudenaar eventually ended up with the Ministry of Defense, which turned out to be prepared to make a training area available.
