The next areas that will undergo the "hotness" will be closely related to the last areas. You can see it beginning now on the North Shore to the West of Market Street into the tip of Red Bank. Also you will see it in St. Elmo on the East side of St. Elmo Avenue.
Finally, just off the horizon we'll see the Lupton City/SW Hixson area along with the Martin Luther King/McCallie Ave. area up to Central Ave. gathered into the "hot". Once this happens the promise of Highland Park that many invested in will come to fruition.
Hope this helps!
Signal is as close to Mayberry as it gets and we like it that way!
