Pemebonwon, S.Br. - Pembine (Hwy 141/8) to below Kremlin Rd (Park-n-Huck or 2.9 miles) (WI)
I see (via satellite views) virtually no sign of any rapids or features upstream of Hwy.141 (other than very minor riffles and rips). There is not really convenient access from Hwy.141, but it appears one could go just north of the river, head WSW on Old Hwy.141, then SSE on Crain Lane to a point virtually under (new) Hwy.141 to park, and carry across the railroad to the river, putting in at the first apparent rapids, and shortening the trip to just 1.8 miles.
