I'm looking for unincorporated areas of DALLAS County for fireworks?

Can anyone tell me where on earth any unincorporated area of Dallas County is? Dallas County lift their burn ban this year, but you still can't use them in city limits, so I'm trying to find any unincorporated part of a set of Dallas County so I can look for a place to shoot off some fireworks.

Thanks.

Practically adjectives of Dallas county is incorporated, there are a few spots south and southeast.
