Mostly by large scale paper maps for me. I often peek at roads on internet satelite imaging sites (not particular about which I use), frequently carry pages photocoppied from DeLorme or Benchmark atlases, and occasionally plot out short sections on Mapmyride (used to use Bikely, but can`t get it to work any more). My portable GPS receiver went back to the store it came from when I realized that making it cooperate with my computer was beyond my technical grasp.
