Didn't see this thread until just now but I'm really glad someone posted it. I wasn't on Route 9 but I've been reading about missing time for a while now, mostly through the lens of crop circle research where you sometimes get witnesses who describe strange lights and then can't account for an hour or two afterwards.
What strikes me about your account is the detail you remember before and after the gap. That seems to be a pattern - people don't lose everything, just a specific chunk. Almost like something paused and then pressed play again.
Was there anything unusual in the days after? Sleep disturbances, strange marks, that kind of thing? I know that sounds like I'm leading the witness a bit but those details matter if you want to piece together what actually happened.
Anyone else in this thread who was in that area Thursday, even just passing through, worth sharing what you noticed even if it seemed minor at the time.
