- Here in Iowa, the temperature extremes that matter are the maximum and
- minimum, not the average. I suspect that on a hot summer day, when the
- daytime temperature is 100 (F) in the shade (and the humidity is 98%,
- although this is irrelevant to this issue), the rail may be heated to
- 120 (F) in the sun. On the coldest winter nights, the temperature around
- here falls to -20 (F) every few years. This gives a temperature range of
- 140 degrees (F) or 77 degrees (C).
