What she's holding does look like it has the kind of rings that would make it possible to fly, it definitely doesn't have the kind of metal hardware you'd expect on a decent flag
It looks like what I got from RCR points a few years ago. They branded it as a “garden flag.” I think it just has stitching around the ring holes? I’ll have to check. It’s not a soft material. It feels more industrial than flimsy.
I wonder if the Nats are going to change their policy on flags in the ballpark now that they are giving them to all the SPH. I took mine to NLDS Game 1 and waved it with my seat mates between innings till that became boring.
Edited: I checked the Nats prohibited item list and this is what it says about flags/banners/signs:
Banners and signs must be handheld and must: (a) utilize only cloth, paper or other light flexible materials, and may not be comprised of or supported by wood, metal or other hard materials that could be dangerous in a crowded public setting, (b) not be affixed to or draped over any part of the baseball park structure, whether facing inside or outside of the baseball park, and (c) be no larger than 2 feet by 4 feet.
So if it’s a 2’x3’ flag with no ring-hole hardware, then it actually falls within the Allowed Items. Whether this is just a coincidence or if the flag was picked with those guidelines in mind, that’s anybody’s guess. There was a lot of kerfluffle when the Cubs fans had their flags taken away for being too big, so at least the Nats didn’t set themselves up for some SPH drama there.
