I'm happy that you made the trip ok without to much damage to your ride. I was suprised to see that we could get higher octane fuel on the way up than we have here. Not sure what you will find in Kodiak.
If you get the time go into the lands end and have a bucket of steamed clams and a cold beer. It's a good way to spend some time watching the fishing boats coming and going. I use to go to Homer every summer and help my dad who had a halibut charter going there. Nice place to visit but cost to much to live there.
