Tenacity of Purpose

Some things just take more effort and time than others. T-3, the huge Pearman support pier near Drum Island is a good example of tenacity of purpose - what Lucy discussed with Charlie Brown way back when. Sparky and I have been watching T-3 ungrow for the past several months and, though we did not realize that this would be a display of Steve's tenacity of purpose, it just turned out that way. I retrieved as many of our photos of T-3 from December to now to show the story. Sorry for the gap around Christmas, both Sparky and I were asleep at the wheel. Here is Steve Testa's variant of Tenacity of Purpose.

It all started with dropping the cantilever section of the Pearman over Town Creek.. The task now is to retrieve the girders and unbuild T-3. November 15, 2005: Explosing T-3 after dropping the cantilever section of the Pearman over Town Creek
