Tools of the Trade
A Global Positioning System (GPS) Ah, sweet friend, we would be lost without you. Literally.
Geographic Information System (GIS) Yes, there's a map for that. Actually, this little baby has a map for everything.
A laptop or tablet. Yes, you can also play games on it, but only informative ones. Like Tetris and SimCity.
A laser printer. Digital is great, but sometimes you just wanna roll your work up into a giant paper tube.
