Hi! Peter! Yes, I do live in Minnesota. If you would be interested in someone trying out the directions before publication, I would be a very happy volunteer. As a graduate student I would frequently need to evaluate written instructions in order to develop scientific protocol for the lab where I was employed. Otherwise, as I mentioned, please let me know if you will be offering a workshop. If there is any way I can arrange it, I will try to be there. Thanks for responding to my previous email and take care. Mary
