Hey sleuths, I am from and currently reside in Hickory. I don't have any insider info yet but I will definitely share anything I can. I'll drive by on my way home from work; it's about 2 miles from my house.
Some thoughts thus far after reading this thread:
I've seen the address 21 21st Ave. NW on here and in the articles. I hope this link works, but if not, you can enter the address on Googlemaps.

Someone mentioned the address system in Hickory, so I'll briefly explain. All the roads are numbers. Avenues go east to west, Streets go North to South. The numbers begin downtown with Main Street and Main Avenue (runs parallel to the railroad tracks), and then increase in number as you travel out. So 21st Ave NW is 21 blocks north of center/downtown.
Hickory is divided into 4 quadrants: NW, NE, SW, SE. NW is generally a good area. You can see that it is close to the country club. They live in a smaller house close to 127, the main road that runs through the old side of town. 21st Ave NW goes straight to Lake Hickory, the body of water some of you mentioned. It's not at true lake; it's just a still area of the Catawba River. I would not be surprised if they end up searching the lake. It gets cleaned once a year and it's not unusual to find cars, dead cows, and all sorts of strange things in there.
The police record shows a different address for SM. I'll check it out and report back after I go to lunch (boss is asking me why I'm not eating, lol).
As far as the homeschooling thing, that concerns me, too. They live in one of the best districts in town for schools--she would probably be in the district to attend Viewmont Elementary. Also, there is an excellent school for the deaf and hearing impaired about 20-30 minutes away (in Burke Co where SM apparently used to work). They accept students from all over the state and maybe beyond, and it is state funded.
I'll be back with more maps and info after lunch.
