...I have been following Petes trip...he had a major setback...
Ouch. I feel for him.
Ian...one of the hallmarks for a successful tour is learning what you want to do, and being flexible enough to accommodate that, even if it means changing plans. You're doing that, and I think its great.
Being able to fund the thing, and going and returning safely in good health are all practical realities that really should be accommodated, but are far too often overlooked in the first blush of the romance of Adventure Travel and the planning related to it. Your approach is a wise one. All accolades your way for dealing with these things and recognizing the need for a change of route and focus. Well done! Nothing is lost by the delay, and you'll be better prepared for a more enjoyable and successful trip as a result. After all, this is supposed to be fun, right? Of course it is, and since you'll be the one in the saddle, it has to be the kind of trip you'd want to take.
Sounds to me like things are shaping up nicely for a wonderful adventure tailor-made to your needs.
All best wishes,
