I have read about some dog parks were basenji's and other trouble breeds are not allowed.
Not to doubt you, but I have never heard this or heard of the basenji being a "trouble breed" like chows, pits, or agressive dogs (I like both chows and pits:) nothing against them) I have never heard them lumped into the same category. Although I heard that years and years ago that some lines were tempermental.
In fact, most people dont even know what a basenji is, or only think the dog looks familiar and then say "oh yeah" when you say it is a B.
However, Bs are trouble in their own way:p
