Check out the Gulches GATRFest ride, this park has all levels and is very small and easy to get around and see other club members doing cool stuff with more built rigs.
I did the same things you did, then got educated and as others of said, ORV parks are the only way now. Its like eating a porterhouse vs a fast food burger. Mr Mike's FS ride will be great for you.
