I posted this to the bike park/dj plans mega-thread, but it seemed worth its own thread as well for this crowd.

Park riders and DJ fans might be interested in a new IMBA book about purpose-built mountain bike facilities. It offers 178 information-packed pages, with essays from more than two dozen expert contributors, and is loaded with 116 full-color photos, plus real-world bike park schematics, graphs, charts, and much more.

Contributors and advisers include Jay Hoots, Lee McCormack, Cam McCaul, Randy Spangler and many others.
