I think the idea behind the selection of the areas was that it be somewhat popular. The climbs in Cheyenne Canyon in Colorado Springs are really awful compared to say, the Sport Park in Boulder Canyon, but the crags are so obscure that no one really cares.
I liked those Cheyenne Canyon routes. Crack Parallel is a good route, cool walk off, nice summit if you scramble for it. Peaceful up there.
Echo Cliffs outside of Malibu gets a lot of grief as being one of the worst crags in the country. I've always enjoyed it.
