Whoa dude! I think you're the expert, and already have the Canonical list. I only knew about Spinterheads and G.P.S. The Movie. And as evidenced by my 3,500 posts, I hang around here a lot (way too much, actually).
I'm going to try to get Splinterheads tonight at Blockbuster, but I'm pretty convinced I'm going to have to order it and get it sent to the store. I'm also going to buy a copy from Geoswag.com. But I figure I'll get them a rental too. No review until I see the whole movie, which will probably be a few days.
There were actually two different Law and Order episodes. The second of which portrayed us a uber-geeks, and ridiculously obsessed with being FTF.
I watched it(Splinterheads) last night. I liked it. Laughed a LOT. I think they portrayed geocaching fairly, made me want to go out and cache!
