Can I call BS? I've lived here my entire life. I practically live next to the Crescent Bridge on Rt 9 that goes across the Mohawk and is parallel to the Twin Bridges pretty much. I've walked the Crescent Bridge at night, I've parked near the little park right off the bridge on the southern side at night. Rode my bike over the bridge at night when I was younger, to meet up with my buddy from Cohoes on Cohoes Central AKA "Dump" RD (Dangerous road, wouldn't recommend inexperienced bicyclists to ride down it at, at night especially [I was stupidly confident in that case]). I've NEVER, I'll repeat, NEVER seen anything around the area to which you speak of. Are you guys on hallucinogens when you see these things? You shouldn't be driving around when you are you know..... Trust, I would definitely like to see something like that myself, and my career requires me to be trained to observe my surroundings, but I don't buy this. If someone has actual proof, which seems no one does, then I might, MIGHT, consider the stories POSSIBLY true. Other than that, stop lying..... Or go to a therapist for help living in your fantasy worlds.
