After 103 years, MotorBoating magazine is apparently ceasing publication. This is from a very reliable source, and is certainly very sad news. I'm told that the July/August 2011 issue is the last.
If it is gone probably the same reason's Powerboat and a few others have gone as well recently. The info is available on line and advertisers don't have the budget to advertise in print anymore. Even my car club forum is better resource wise over the club magazine!
