Hi Jon, to answer your question I would say many people had their encounters before bigfoot became so popular and why would someone write down the date they saw what they saw. But I feel you on being attacked on here for asking a question that wasnt in the norm on here. Ive been tore apart for asking a question before. Anyway ooh-raH for your service!!! I assume you are desert veteran as I am. Also the get over it move on remarks I saw are total BS too.
