someone close should print some flyers and post in some parts house, maybe the owner will recognize the stuff for sale. At least call and ask questions put some heat on the guy.
Yeah, a Yellow Jacket something or another.........different testers and some other stuff....
If the poster was any more vague he would have had to post a blank screen
"The problem is the average person isn’t tuned in to lifelong learning, or going to seminars and so forth. If the information is not on television, and it’s not in the movies they watch, and it’s not in the few books that they buy, they don’t get it" - Jack Canfield
