I live in the Atlanta area...since I have a sighted husband, I don't usually have to use mass transit or cabs. I have been told of numerous circumstances where cabs, most driven by what sound to be people whose first language is not English, trying not to have dogs in the cabs citing everything from it's against the law to allergies to religion. I do not think that many cab companies are specifically training their employees the laws involving dog guide usage. I can just see one of those cabbies now...who fights against a dog and person entering their cab if they are confronted with a miniature guide horse and its owner...smile Nancy
