Merlyn, one of the symptoms of "Long Walk Fever" is the need to plan a long walk before being ready for it. It's likely you will find it's not possible yet unless you are very unique. Don't disappear if that happens. Just learn how to get ready.

From your gear choices so far, I can see you will benefit from some practice runs. The alternative is to throw away a lot of things along the way. Either way works.

(Edited to delete Trinidad idea. It's further than I thought.)

I'm helping someone plan a very long walk which he is perfectly capable of doing. I'm halfway through the planning and I've found it's just a series of 20 mile day trips, so that's kind of a magic number.
