I was playing kick the can with my brother and a bunch of our friends alongside the susquehanna River late at night in Halifax Pennsylvania, it was probably 1993-95 maybe. I was being chased by the team that found me along the river Bank . There was probably 6 or 7 of us running along the bank when a huge triangular jet or something silently flew down over top of the river . It was really low and looked like it may have spanned the whole way across the river . It was some crazy ass shit . Either it was really low or it was so big that it appeared to be as large as that portion of the river, we all dropped to the ground and layed down in panic(not sure why, just instinct I guess lol) . We all took off running home then to tell are parents what we just saw ,none of them believed us of course . Everytime we are together it gets brought up in conversation, because back then we didn't know anything about UFOs . Almost positive that's what it was.
