It’s possible I noticed this before but it’s hard to say. The Firearms Blog has a picture of me at the event which inspired Boomershoot: At the bottom of the post is a picture from the 1997 Blanchard Blast.
I stumbled across this while reading Deplatformed: How Big Tech Companies & Corporate America Subvert the Second Amendment (very well done). This post linked to PSA: Microsoft’s ban on using its services to promote guns. Having worked there, and my daughter still working there, this is extremely annoying. And that blog post led to the Microsoft Gun Club post where the picture was found.
