I have been to every Cub-A-Rama show since the 1st one in 2002. I live only 40 miles from it. When you open the website you posted, scroll down and the picture in the lower right hand corner is of my kids and I plowing at the 1st show in 2002 with my 1st Cub Cadet, a model 70. Still have it today.
Lot of memories made at Cub-A-Rama's. Met and got to know a lot of great people there. The show may have reached its peak a few years ago, but it is still alive and for sure worth the trip.
