his profile shows that his last visit was November 6th 2007.
Maybe got other things to do in his life? I think sometimes people just get busy and for whatever reason, don't come on here as much.

I don't want to sound callous, but I think he passed away.

There was a message on the top of the ATS logo for the longest time that read:
R.I.P. Shots.

As a matter of fact, the thread should still be around somewhere, I just can't find the link to give you. I think either it was his daughter or wife who came online and posted a big post saying he passed away.

If you look at his comments section you can see the messages people left for him.

Sorry to have to tell you like this.

Yes, Shots passed on a few months ago, lot of folks were active in the thread mentioning his passing.
