A track like that is awesome but it has its drawbacks when it comes to organized racing. The layout is amazing and extremely entertaining for the racers. But all those different elevations everywhere is a nightmare for the marshalls. If it's a track built by a few people just to have fun with than it's all good because there's no stress. If it's meant to be a race track then there's going to be injuries to marshalls trying to get to a car in a hurry. They're going to trip and fall, break an ankle and fall flat on their belly and be hit in the face by a buggy coming at 35 mph breaking their jaw and knocking off three or four teeth.
Good times good times.
