Houston and Galveston evacuated 95% of their population. At best, New Orleans evacuated 80%, leaving behind their most vulnerable -- those without cars or resources, those in nursing homes and the disabled.
By contrast, Houston and Galveston used buses to take out those without resources, those in nursing homes and the disabled.
Where did you get your 95% number from?
