It was a nice story, a happy ending, and showing that the government may actually be trying to help, and not hinder progress. I think to often we are to quick to slam governmental actions. The need to prevent contamination is a serious issue, look at the earthworm problem I read about in the North east killing forest, invasive species both animal, and plant issues. (I don't remember if the worm post was one of yours or someone else's, so much reading.) Thank you for a wonderful story, and nice conceptual view of the government and it's scientist.
