OK...
There is indeed a NAMGBR annual convention every year. This year's event is MG2007, held in Sonoma County, California. See
https://www.mg2007.org/ for information. It has the makings of a great gathering.
NAMGBR's MG2008 will be held in Valley Forge, PA. The C Register will be joining forces with the Bs for that event. I do not believe there is a website available at this time. Jim Schulte is event coordinator for MG2008.
NAMGBR's MG2009 will be held in Colorado and hosted by the MGCC Rocky Mountain Centre. Robert Gloyd is contact from the local club. Again, no website at this time.
NAMGBR's MG2010 has yet to be "awarded"...I'm sure that the Register Executive officers and Tony Burgess, NAMGBR's Convention Coordinator, would be happy to discuss this with local clubs interested in hosting a convention.
That brings us to MG2011, the next scheduled all-MG Register gathering for North America sponsored by the North American Council of M.G. Registers. It was decided during a MG Council conference call in March that there would indeed be a fourth event to be held in 2011. No location nor host club has been decided at this time, although action has begun to find an interesting and fun locale for MG enthusiasts to convene upon sometime during the summer of 2011. Regions outside of the Midwest are indeed being considered for this event.
So there you have it...hope to see you all out on the road sometime this summer!
