During this holiday week, as you look back at Christmas and prepare for the New Year, it's a good time to settle in and catch up on the latest edition of Sine Waves.
This current entry seemed like an appropriate theme for the holidays and a lead in to the 3rd year of the series.
So, find a comfortable place and enjoy.
While you're at it, think about all those stories from your time in the field and share them. Our stories are your stories, we all share the same type of experiences.
We would love to have your input.
