The images are all indoors at the Washington State Convention Center downtown Seattle. We held an annual technical conference at the WSCC every year.
The pictures are of the show floor from the convention at a night we called Ask the Experts. Yes, even though I was there, they let me in despite the fact that I was not an expert.
The hat (blue) was made for me by a co-worker and I promised I would wear the hat. I did actually wear it instead of the orange hat the rest of the experts had to wear. I may have dodged a fashion bullet there. At least my hat looked cool.
