1990 Miyata 1000LT
I always like taking pix of bikes here- the trail is on a high berm, there's a driveway at the bottom running parallel with the trail, power lines overhead, and a power/phone line that run along the driveway. Under most circumstances, you don't see the power/phone line (if you magnify the view you can see them coming from the wood pole) and I'm not talking about the lines going to the large power line pole in the distance.
One morning I was riding along, and I saw a bird. It looked like he was sitting, but there was nothing there. He was directly beneath the overhead lines, so I was thinking he must be hanging on to something suspended from the lines above... but he looked like he was sitting on something... but nothing was there. It took a VERY long time to figure out there were other lines that weren't visible in the morning sunlight/shade.
