 :::I have tinkered with it a bit.  There are areas that are both inside and outside of the city limits.  I have included both in the article.  Hixson should be Ashland Terrace to Red Bank/27 to Thrasher Pk. to the river.  Anything north of Thrasher is Middle Valley or Lakesite.  Anything west is Red Bank.  Anything south is Lupton City/Rivermont.
