I have paddled about a 120 mile stretch from CR 612, north and east of Grayling, in the headwaters down to Glengary Bridge which is near the Mesick area, headwaters of Hodenpyle Dam. If you have interest, there is a livery I work with that could easily spot you and has great, reliable service.
I paddle mostly the stretch of Smithville (M-66) to Harvey Bridge (Rd. 19). The upper stretch around Grayling is more private, while downstream of Smithville is a whole lot of state land.
The World is my country, all mankind are my brethren, and to do good is my religion.
