@theluthier – this looks like a very cool project to collaborate as a team. While there will be activity for a month, it is more bite-size compared to the backhoe project. It is very evident that you have planned and thought this project out very well. Even providing reference training material, which will no doubt reinforce lessons in this class. There are a few classes in your helpful content lists that I have not gone through yet. I will work on viewing the rocks, clouds and tank courses prior to April 6th. I recognize that running a class like this disrupts your normal daily routine. Many thanks in advance – I am definitely looking forward to collaborate on this project.
