I saw something weird like that in Portland once...
This was almost 10 years back, but it's still fairly vivid in my mind due to the apparent mysteriousness of the sighting.
It was a weekday morning, probably around 8, and I was driving home after my regular shift at the mortuary. There was a man walking on the sidewalk of a busy street in an upper-middle class neighborhood. He kinda stuck out because his outfit looked to be of high quality, expensive pieces, which kind of drew the eye, yet he also looked like a straight up Bond villain, with black pants, a black, leather, car coat type jacket, rolled-up stocking cap, and leather gloves, all topped off with Eastern European features on a serious looking face. He was also carrying full-size bolt cutters, which were tucked upwards under one arm, like he was trying to casually conceal them and hope no one noticed.
I obviously don't know why he was carrying bolt cutters down the street like that, but I figured parking sucks in PDX, and maybe he got stuck with a shitty spot around the block from where he was either delivering a much-need tool to a friend in a pinch or doing a B&E while hunting Jason Bourne.
I only saw him for about 10 seconds as I slowly passed by while driving and, ever since, he pops back up in my mind from time to time and frustrates my thoughts with a lack of closure as to what he was actually getting up to that morning.
