You need like a James Bond villan lair....with sharks that have lasers strapped to their dorsal fins......currently I'm in the process of building a monorail system that is 5 miles underground near my house....first you go through the biometric scanner, we take a DNA sample....take an elevator down 5 miles.....disable the laser grid and poison gas...unlock the blast doors and you can easily make your way down to our hermetically sealed grow laboratory. The monorail goes all the way from the Tri-State area to the Rocky Mountains.....it's really been the limiting factor so far.
