Reading Extreme Alpinism (and Kiss or Kill) was both funny and informative. As long as there are boundaries to what people think is possible, then there will be people pushing those boundaries. Though Twight's rage (at least the rage that live is Kiss or Kill) is comical, what will be really funny is the person who tries to push the limits beyond what Twight has set.
I'm glad Twight wrote these books, because it is always interesting to hear what the Extremos are doing. And he must be somewhat accurate with his information because he is still alive.
