We put in below the Ayers Island Dam (off Ayers Island Road). We took out below the park and play hole off Coolidge Woods Road. The river is about 1-1/2 miles long with a couple of nice play spots. The first major rapid is about 1/4 mile downstream. The easy route is on the far right. Paul’s line is right down the middle. Joe made it look easy.
I got spun around in the first drop and ended up sideways in the hole (as you can tell from my narration). I worked my way out eventually, and I ran the rest of the rapid backwards with a boat full of water. It wasn't pretty, but I made it through.
From here, the river is a series of small rapids. The last rapid sweeps gradually to the right as it passes through a couple of ledges along Coolidge Woods Road including the park and play ledge - a popular summer play spot.
