Jon, if you wanted more detailed information you could have simply asked for it, rather than leading off with your self-pedistalizing quip about finding my claim hard to believe.
My home airfield is S44, which is not only under Seattle's Class Bravo, but under McChord AFB's airspace as well, so I tend to check things pretty close. When I just go pedaling around the area I get a 50 mile area briefing. Had I mis-entered the identifier, which I triple checked, I would not have recognized any of the associated reporting stations for METARs, TAFs, and NOTAMs. The previous week had shown a VIP TFR when Biden was in town, which was much smaller than this 30 mile TFR, using the same area brief.
We all make errors, including controllers and briefers, so my point is, don't take a CSC DUATS brief as gospel.
I am considering using a different DUAT service, anyone have any preferences?
