Summer time...
Gripping (for me anyway coming from the cornfields, with the sandstone grit of Kickapoo Falls being the only decent training area within an hour and a half)... No real Epics though..., just milestones reached in terms of degrees of difficulty...
His father, Tom Hornbein and much of the rest of the team spent a great deal of time training on Longs Peak for the West Ridge Route... That story has its own book, aptly named "The West Ridge" ...
Worth a look, it's a page turner... Horbien is either "the" or..., one of..., the principal authors.
