  1. Thanks very muchly for this. Righteous stuff, very righteous stuff.

    The comments by the last John Unertl his-own-self were poignant.

    • Im going to tell you something that is going to make you sad. About a year after I posted that, I got an email from a Unerlt employee who worked there and worked there when the last John was working there, He was very Angry at him and refuted a lot of what he said about his Dad and the business and how it ended, I emailed him back asking him permission to publish his email but he never emailed me back. to make it worse, when my lap top broke I lost the email and now i cant even post a redacted version of it,
