There are LEGOmaniacs and then there are LEGOmaniacs. James Burrows is a LEGOmaniac of the first order. Check out Beyond the Brick’s video of him giving a tour of his massive dinosaur themed LEGO park, complete with functional CoasterSaurus II roller coaster.
There is some actual science behind that coaster, since James said he took a college course to understand the math and physics of coasters so he could make the loop-de-loop work. Now that is taking your passion seriously. The whole 125,000+ brick theme park is incredibly impressive, and loaded with lots of cool little details.
Remember it has a WORKING LEGO rollercoaster. WORKING. That makes this LEGO theme park one of the best ever.
