As usual I am a late comer to social networking, and yes, I recognize that having a blog does not constitute a network, nor for that matter being social.
The name for my blog is two fold. The first, being a geophysicist, my job is looking at signals in time and determining horizons or "boundaries" that relate to real events in the subsurface. The other part, is that I have many hobbies and am constantly trying to balance them with my work and my family, which currently consists of my wife and dog. I guess I thought the name is marginally insightful, and punny.
