As for restrictions, it is not posted, and as stated, it is public property. However, probably wouldn't open carry with the crowds around, but that's just me.
If you plan to come out, watch their Facebook page or website for updates related to weather. https://www.facebook.com/planoballoon/?fref=ts or www.planoballoonfestival.org
And, you can't get out to the balloons, but my balloon has the Fox 4 / My27 banners on it.
