When I was a kid I started collecting USGS topographic maps of places I wanted to visit (pretty much the entire Sierra Nevada). When I was in college I decorated my walls with maps of remarkable places. On more than one backpacking trip I had to show the leader, tactfully, that we were heading down the wrong trail. Today, maps are among my favorite graphics to produce. Most are slap-dash location maps for environmental documents, but occasionally an opportunity to make something pretty nice comes along.
