This is maybe a little random to post on a Mac board, but it's the best online community I know of (I don't post much, but I've been a regular for several years), and there's quite a range of experiences here. Anyway, I'm working as a volunteer in Ecuador right now, and when my time is done here I'm planning on taking a trip through South America, including a trip on the Incan Trail. I'm wondering if anyone here has any recommendations on good guides (licensed compaines who go on the trail, not books) for the hike. Any other especially pertinent comments or suggestions are appreciated as well--I'm thinking I'll do the 4-day trip, any thoughts on that? Thanks!
