Any areas with a MLK boulevard are not places to get out of the car.
Next time you got to Dallas, I was going to invite you along on a stroll down Martin Luther King from Cesar Chavez to Malcolm X Boulevards. Only 8 blocks, and we could go past the Muhammad Mosque a block or so in, and end up at the Islamic Center of South Dallas.
Streets might be busy at rush hour, so after midnight on Saturday night might be best.
