You can download and print individual USGS quads if you want

Everyone uses the USGS quads which means you need a lot, I keep a few pdf's and printed and use a handheld gps for the rest. It can run 24 hours on a pair of rechargeable AA's and I keep several more pairs of AA's ready to go (low self discharge so they can sit charged and waiting)
