Searching for insulators along the Transcontinental Railroad can make for a long and grueling day. Very hot or very cold temperatures along with sun, wind, dust, ticks, snakes, and sore feet, can leave one wondering, "why the heck am I doing this?" My son Sean and I have had our share of long days with nothing to show. Finally however, after many miles, perseverance paid off and we found a VNM threadless insulator.
