Oh I forgot what really got me into looking into this. On one of my husband's combat deployments he used to ruck through the mountains of afghanistan. The locals would point and say, no go, and the translator would tell him there were yetis in the mountains. Almost everywhere you go where there are indigenous people, there is also knowledge of these kinds of "creatures." The fact that these guys were telling him not to go and seemed afraid really piqued my interest.
