I registered on www.ExpeditionPortal.com after many, many recommendations. I now realize I should have done this ages ago - the expanse of information is a little overwhelming. At some point I'll filter through the posts and find some things I can use.
There's one fella on there that just completed an Alaskan road trip, much like what I'd like to do... only I believe he was gone for a month or more. I have to work an abridged 3-week version. But his testimonies about some of the destinations, and his photos will be a huge help.
