Rails: Up and Running, 2nd Edition

Colophon

The animal on the cover of Rails: Up and Running, Second Edition, is an ibex (Capra pyrenaica). Found in the mountains of Europe, central Asia, and North Africa, the ibex spends most of its time at an altitude of 7,500 to 11,500 feet. The ibex is known for its impressively long horns, which can grow up to three feet on males. During mating season, ibex males bang their horns together in intense battles over mating rights.

Although the physics of such a feat seems dubious, according to legend, the ibex’s horns were so strong that, if threatened, the animal could hurl itself from a precipice and land unharmed on them.
