Do you dream of one day becoming an old, crusty climber who talks about how tough he/she was back when climbing wasn't full of a bunch of pansy, gym climbing, "life style" climbers? Do you have a desire to carry around hundreds of pounds of gear to crags that have not been climbed since the 80s? Do you want to tape up your hand and shove your body into a crack for 100s of feet? If you said yes to all that then become a Trad climber and buy the north book, there is a lot of trad up there. Also a few sport crags, really good ones, like actually really good ones, probably better than the other ones.
