Thanks for the reply, Greg. Since the Thunderbolt is built around terrain, I would need your help in figuring out how to create realistic terrain. I would rely on you all to build it. I would purchase the bricks. I could then come up sometime and help install the coaster structure and track. Hopefully you all have the connections in town to have it displayed somewhere. I know people at the park so perhaps we can get it on display there. I’m by no means an expert Lego builder. I can, however, build a mean roller coaster. Lol.
