We finished Imlay in a very light rain. After Greg and I had dropped into the Narrows, it started to downpour. Chapin and Tom had to rappel down in the heavy rain.
I have never been in the Narrows in a full thunderstorm. It was outstanding. The pour offs begin to flow and the river rises to where it is mostly floatable. The Narrows are best viewd from your back.
I still get giddy thinking of how much fun I had!
