My husband and I really enjoyed this experience; when else can I drive heavy machinery? We were in the excavator, because I read that we could do more things with than the bulldozer, which did indeed seem to be true.
It took about 20 minutes to really get the hang of how to operate it but the instructor was able to direct us via our headsets. Aside from digging a big hole we moved large tires and some basketballs which required a bit of finesse with the controls-- it was all very fun.
I feel the $200 per hour price tag is a little high but it was worth doing once and I would highly recommend it.
