Since a few seem to miss or not appreciate my sense of humor, let's dig a bit deeper and address the meat of the matter shall we? To Sunflower I don't know what kind of personal swipe you're trying to take, but there's no joke on me. Birds commonly ride on hippopotamai as well, so what does that have to do with the price of tea in China?
If your implication is that pigeons ride trains in New York, ergo bigfeet ride trains as well, allow me to introduce you to the concept of apples and oranges. Random birds landing on random trains and just happening to go along for the ride is quite a different concept than said birds deliberately catching a lift from the Brooklyn to Manhattan for a fine dining experience. When you can demonstrate that earthbound forest animals such as bears, moose, elk, bobcats, deer, et al hop trains for the express purpose to commute to the next town or feeding ground over, you might have something that could potentially spill over to an unknown primate following suit. However, I'll go so far as to state that you will be exceptionally hard pressed to find any of these animals even accidentally going for rides on trains, much less doing it on purpose. Be sure to let us know when you can provide those documented reports. To go one better, there have been numerous accounts of foreign nationals hiding in the landing gear wells of airplanes entering the US, so why no reports of bigfeet doing that? On second thought...don't answer that question...I wouldn't want to be the one responsible for starting that bit of bigfootery "fact."
Moving onwards and upwards, I would be more intrigued to see why the concepts such as those that Nathan states: "Primates take shortcuts to better them selves, from stealing food to riding on moving objects to get where they want to go," and "Nothing is off limits to brainy primates if it is advantageous to them" haven't been taken to task yet (not him personally, but the concept). Overall, I am prone to agree with those statements, albeit with small reservations. Specifically, I'm not aware of reports on monkeys deliberately hopping trains to go places...conceivable I suppose, but if so, I seriously doubt they have a destination in mind. Nonetheless, this philosophy doesn't jive well with a certain cadre of folks on here that have shall we say...a more "liberal" view of bigfoot.
I don't have to dig too far to find all kinds of comments with emphatic statements that 'bigfeet can (and have) operate digital cameras if they choose to, but don't want or need modern human conveniences like fire, tools, or wheels.' I can't wait to see the verbal contortion act to explain away why these creatures, who as so many on here say "is smarter than humans" consciously choose to live like animals or pre-humans, yet have lower themselves to modern human level in order to catch a train to go visit relatives.
