Probably 90% of all glass insulators still in use are on the railroads.

Bowl-shaped suspension insulators can be found in Southern Oregon. This is in Grants Pass right along interstate 5.

Here's a "Lightning Stool" as used in fire lookouts. It's a remainder from the crank telephone years. If a thunderstorm was near your lookout and you needed to report a fire, you would stand on the stool before touching the telephone to avoid getting shocked by the static buildup on the lines. They are still in use in many lookouts, although most report fires by radio now.

There's still alot of glass up in the air - this is on Rte 66 near Seligman, AZ.
