Good point. I did notice the "dome" was not a dome but a blip and then extended layering very low but lengthy along the NE horizon. Several times there would be a train light or a car light off in that direction too and hoped it wasn't an offroader. The Yuma dome was very small. I'm used to domes spreading towards 45 degrees and these are 10-15. Jack Jones > Russ, > > There has always been a significant glow in the northeast from > Phoenix.
