I've been to 5 in Evansville Indiana, 1 in Louisville KY, and 1 in Nashville TN. I really enjoyed all 7 of them...No complaints except the concession refreshments were expensive. The new additions such as the monster truck 2 wheels skills challenge, the speedsters, and the quad wars help compliment the overall entertainment.
My 2 favorite events are the monster truck donut contest (cause I love watching the drivers spin the trucks into a big cyclone) and the monster truck freestyle. Not to mention some of the new, up/coming drivers such as: Justin Sipes (Team Megalodon) and Brandon Vinson (Team Grave Digger) normally turn solid performances . My favorite monster trucks are the Ram Team: Raminator and Rammunition. Above all I truly felt like I got my money's worth at all of these event's.
