Just to note. The New Testament is intended to be used hand-in-hand with a Delorme Atlas and Gazatteer, and the directions are written to exactly match these statewide topo maps. These maps are $20 per state, and much better than anything that we could design. This is explained in the instruction manual section, which most of you will never read.
CRC is funny. Those old schoolers are goofy.
Our ratings are very consistent with CRC2. The main difference is that we attempted to correspond our ratings with various flow levels, and we separated out individual rapid ratings a bit more.
