This is another Interstate 81 light streak shot, taken the same day and time as the one you saw yesterday.
This one made me chuckle a bit when I saw it blown up. Take a close look at the red streak taking a swerve toward the top right of the photo. Apparently, we had a driver who didn't know whether to bear right and stay on 81, or go straight, toward the 84/380 junction.
I like doing the slow shutter speed thing, but it's tough find a place with a good line of sight. There are fences lining most highway overpasses these days, and that's a good thing. It's also difficult to find a place where you can shoot safely.
I'm on the O'Neil Highway in Dunmore, looking over Interstate 81. There is no fence here. There should be. I donned my reflective vest and snapped off a few shots. Admittedly, it wasn't the safest place in the world, but there wasn't much traffic at 4 am.
I got what I was looking for, and took off. The shots could have been composed a little better, but I didn't want to be overly risky and spend a lot of time out there.
I'm always scouting for interesting, yet safe locations.
