Glad you had such a good trip! MikeO and I just spent a week riding some of the same roads you were on, but a week ahead of you from the sound of it. We had a lot of rain too, but that's Alaska for you.
Two years ago I rented a bike from Phil at Alaska Rider Tours and had a great trip on the Kenai. Phil was immensely helpful and friendly. I'd work with him anytime.
Thanks for your report!
