I know it doesn't make any sense, just watch the video. Sort of H2 old-skool in a way, so it's great fun. Terminator wrote this up for us, thanks Term:

"RandomCTG posted an interesting thread yesterday, that's well worth the watch. He demonstrates such a simple little trick, it makes you want to kick yourself, a simple tutorial on how to get a Banshee into the Zen Garden, and to top it all off, a wholoping vehicle collection in the Zen Garden, consisting of 12 intact Banshees! You don't want to miss this, for it is quite a feat! Fantastic work RandomCGT, you're becoming well known around these parts."
