@ivo I am not sure how much technical knowledge one needs to be a tester, but as a member of Michigan Geographic Alliance, and a teacher trainer, It would be neat to make use of this for students or share with other members. Lessons can be created and material are given free to teachers from the teacher trainers in the Alliance. There are alliances in every state and they were all stated with seed money from National Geographic. What do you think?

@ivo Would like to have seen depth of water so one can tell if there are surges and how deep they might be.
If able to be more specific, go into neighborhoods or possible specific addresses.
