I mentioned at the meeting to read as many Internet resources as you can to prepare for your trip. The general idea being 'learn from others' mistakes.' One of the best resources is www.advrider.com, where the world adventure riders go to post their adventures.
There is a specific Alaska forum there and a single thread titled, "Alaska Primer". That is a good starting point if you have not otherwise started your research and planning.
