Probably the best time to film, to be honest. A lot of the places he went to would be a pain in the ass to get to during a busy day. Knowing the backroads is a godsend. :)
I wish there was some way he could've shown that Klyde-Warren park is built so that it is suspended over a highway but I doubt he'd want to risk flying it somewhere where he could not easily retrieve it if it fell.
It supposedly has its roots in "Dunsail" which is a naval equivalent of "that dog don't hunt".
But the Trek reference is accurate. TOS - The Ultimate Computer.
