I've eaten and also have seen eaten some strange things while hiking that most people probably would not eat if they had more choices. If you've seen (or eaten) other strange things, please share your experiences.
ps. i couldn't believe it when i saw people eating raw pork (that sat in the sun for more than a day) and beef and not get sick here in Thailand but that's not the trail so i didn't include them. Also many different kinds of bugs are eaten here as a delicacy, some alive, some fried. (my girlfriend loves beetles when she's drinking beer)
