Do you still have his mailing address? Have you attempted to locate his phone number using that information? I'm assuming you at least still have his last name since you had to have that for the MO.
I did a quick search and his last post on CEG was a month ago and 2 months since this forum. We do have several members in the St Paul area, which is where I beleive he's from. One of his posts mentiond a city called "Crystal" which I think is Crystal Lake, a suburb of St Paul.
Any of you twin cities guys know Tony personally or have met him? Please contact Cart99 via PM if you have any personal contact info on him. Also, please post here if you can/will help in contacting him, just do not post any of Tony's personal info here.
Thanks,
Rick
