I know I didn't get a close up because my camera stinks for close ups. I think
Chris may have gotten some but he hasn't uploaded his pic's just yet. If we
don't have one now, we are having a meeting in a couple weeks and we will make
sure to get some then.
For now I will try and give you an idea of where it was located.
This is the crossing and the sensor is below the Caboose (you can see the
wire).

Now we only had the sensor for the last day so that limits the number of
pictures it could be in. I am pretty sure someone was taking a close up at one
point though. Anyone?
