Guy at work's mother is an administrator for the OKC FD. He called her and asked if charcoal and gas grills were OK to use in OKC.
She checked and told him emphatically NO! OKC's burn ban is not the county's burn ban.
Hahahahaha...of course if you call and ask them they will say over the phone that its not allowed. But they have made no effort to post such a restriction via the OKC web site.
