MOTS,
You must consider a few things before attempting to discuss something like your sighting, specially here. First of all, what are you attempting to achieve? What are your goals?
I hope its not to trying to convince us by presenting another tidbit of anedoctal data. By the time you've been around here, you probably noticed anedoctal data such as sighting reports is problematic. Just in case you have not, I suggest you to carefully read these links

A search through the forums using keywords such as eyewitness reliability will certainly bring you a huge ammount of valuable information.
I also hope you are not looking for confirmation. Many people present a report (UFO, ghost, etc.) and say "EXPLAIN THAT, YOU SKEPTICS!" The problem is, most of the times there's no way one can truly "explain", based mostly on an account, what happened decades ago! "I don't know" is a simple and honest answer. And when faced with it, some people say "HAHA! SKEPTICS CAN'T EXPLAIN, SO IT MUST HAVE BEEN ALIEN SHIP/GHOST/ETC.!" However, "I don't know" is very different from "it was an alien ship".
People might present you explanations, possibilities, ideas, guesses, etc. Some will be plausible, while others will be far-fetched. In any of the above cases, if you already have your mind made up, the discussion is useless and the ultimate outcome will be you getting angry because people are not accepting your previously stabilished notion.
However, if you are looking for explanations other than "a bigfoot", you will find them. And some will be quite plausible, despite the fact that they will not involve a bigfoot. In the end, we will not be able to say "this is what really happened" due to the time span involved, the nature of memory and the lack of evidence. You may as well say "I still think it was a bigfoot". OK, its your right. But it does not mean it was. The same is valid for us, we can say "We don't think it was a bigfoot", but we can not actually prove it was not*.
However, when faced with alternatives, you must investigate them with impartiality, you must leave your personal feelings and beliefs behind. You must be aware of the possibility that you may not have seen or had a close encounter with a bigfoot and take it in to account. If you can not or are not willing to do so, then there's no point debating your experience here or anywhere else.
*I don't want to enter in to a long OT discussion, but in some cases, for all practical reasons, we can indeed rule out this sort of possibility and prove negatives. Open a new thread on it if you want a deeper discussion. In the meanwhile, consider this: How can you prove there is not a teapot orbiting the Sun beyond Mars? Or a black hole orbiting Earth?
