Raw Hyde and BMW have courses on opposite sides of the country. The BMW course in Greenville looks like a winner to me as I'm often in South Carolina.
Neduro, one of our own has several offerings also. PM him as google failed me.
The BMW MOA GS Giant program also looks interesting.
F650GS -- sold -- what's next?
