Might be nothing....but. Re: Q post 3525 with [ 93 dk]
Ok, we're dark for 93 days, but the spaces have to have meaning too. Near as I can replicate in various fonts is four spaces before, seven after "93". If this is the case could it be 4397? That's an antibody, an address in DC, a geodetic coordinate system for Europe.....
The one interesting return was an address in DC. Reverse lookup and a little sleuthing brought up the owner, who shows having two properties in Bremerton and Bothell Washington. Wasn't something bad supposed to happen in Washington?

Or, For 937. That's mostly an Ohio area code for Dayton and Springfield. Ohio's Senators are Rob Portman (R) and Sherrod Brown (D).

Or [ 93 dk] Flight 93 dk (don't know)?

I've tried similar searches using 3 and 6, 5 and 8, but nothing promising. Slow on end, can't get on kun, might as well go to work.
