Check out today's New York Times for a lengthy piece about Gym Jones.
It's a shame there's so much bad blood between CrossFit's Greg Glassman and Gym Jones' Mark Twight. In my opinion, both methodologies are variations on a theme, and vastly superior to "mainstream" approaches to fitness. They've clearly influenced each other -- Twight's gym started as a CrossFit affiliate, and CrossFit's recent embrace of stationary bikes brings to mind Gym Jones' fondness for AirDynes.
Also: Something tells me I'd really get a kick out of Jones Crawl.
