Close up of the Bonneville pole tags. T TP means Timber Tap pole 1 over 1, or pole 1 in 1 mile. The metal letters use abbreviations like TK for Tillamook, FG for Forest Grove and K for Keeler sub. A typical pole will be tagged this way showing where the line originates and where it is going. The yellow tag says Bonneville Power Admin. Oddly, there are no fences anywhere around this switch group and one can walk in from the highway. The Tillamook line switch group is shown to the left.
