Just did the Saco River this past week end. Put in at Fryeburg fair grounds. Camped on the River. About 7-8 hours down the river you will come to the canal for Pleasant Pond. You can camp right there . Fish the pond for a couple of days. Look it all up on google maps.
Caught 60+ fish from Sat to Tue. Plenty of Larrys, Small Mouth and Black Bass. Also some crazy big Pickerel. River shiners ,Smallies and Larrys on the river . River can be slow, but plenty of entertainment floating by the camp areas.
