man standing close to frontier drive exit

hey guys, did anyone else encounter a white man with tattered clothes looking very disheveled and in a daze standing at the very edge of the grass on the frontier drive exit off fairfax county parkway, right by the franconia metro? i was driving back from kingstowne into springfield at around 6-7pm today and he was just standing there staring at the ground, dangerously close to the street. really spooked me because ive seen all the panhandlers (?) and homeless folks around here, he wasn’t one of them. he seemed like he was in a daze, his shoulders were sagged, i think he had glasses on and his clothes were baggy and tattered.
