I came across an older post that asked if anyone was using Piezography in Minnesota. The question is still out there. It would be nice to see others that are using this and get their feedback since we have to fly blind. I would love to be able to attend the workshop in Chicago on the 25th, but it's not possible for me to travel or be gone for as long as it would take to attend. But it sounds like that is something that would be great learning experience.
