My wife and I enjoy a show on Discovery called
Expedition hosted by Josh Gates. It's one of those scripted travel/adventure shows where he goes traipsing off to the Peruvian jungle to search for a crystal skull or the such. I leaned that there was a 4 part special mini-series of this called
Expedition: Back to the Future. Quite a fun watch it's also available on Amazon.
In the 4th episode they go looking for parts to build a new model Delorian. That location is called
Apex Surplus in California. Now there's a lot of places to buy movie props & memorabilia. But this is the place FX wizards or prop masters go to actually build that memorabilia. It was incredible to watch in that episode when they visited. The website doesn't really do it justice. But here ya go. Get ready to geek out:
