Roasted guinea pig - Mary's favorite

We expect a few challenges on our trip, from what we've read and heard from friends -- water quality, language, altitude sickness among them. But we're at least mentally prepared for these chanllenges. However, the most interesting challenge will be food -- what to eat, what to experiment with. Our Lonely Planet guidebook mentions a few specialties for the gastronomically adventurous, all of which Mary has already vetoed -- roasted guinea pig (image), bull penis soup, and cow hoof soup. If this keeps up, we'll lose a few pounds.
