We go there all the time. Never the same. They have a contest with the big old Rumleys in which the operator has to back the machine up and touch a bowling pin with the back hitch without knocking it over. Some of the contestants are teens of both sexes who run them with absolutely amazing skill.
Once they had a 16 bottom plow pulled by a steam engine with a dozen people standing on the plow. When the engine dug in at about 50 rpm watchers started to step back because they felt the boiler was going to blow. Never missed a beat !
