This creation was both fun and a bit challenging, cause all of the peices are turning upside down. It's actually a few days ago, since I took the photos, but I couldn't (in somehow) get acces to MOCPages, so I had to find another computer. Hope you'll like it and please leave a comment.
Nice MOC. In response to your question, most large creations are built in sections for easier transport. Also most are packed into boxes and containers and can fit into cars. Sometimes if people are traveling a long distance they have their creation ship or carried in a trailer. Hope this helps.
