It’s a little hard to tell, actually, based on the Walk Score index recently released by a Seattle software firm. The company divides the neighborhood, calling the area bordered by the Tollway, Northwest Highway, LBJ and Central as "North Dallas" — and everything west of the Tollway, all the way to Farmers Branch and Irving as "Preston Hollow," which is, of course, ridiculous. Anyway, among the 26 Dallas neighborhoods that were ranked, "North Dallas" came in at No. 11, with a walkability score of 55. "Preston Hollow" was 13th, with a score of 53. Both scores are considered "somewhat walkable." The West End, ranked as a "walker’s paradise," and Oak Lawn topped the list, and South Dallas ranked at the bottom. … Among the 40 cities ranked overall, Dallas was No. 24, the highest-ranking city in Texas. (Houston was 26th, Austin 29th, and El Paso, San Antonio and Fort Worth ranked 31st, 32nd and 33rd, in that order. (Jacksonville, Fla., was ranked least walkable.)
