Was under the "assumption" that GSM (Clarksville) was a posted building. So, I did the usual trick of cutting through Sears (no postings on any doors, inside or out) and was about to enter the main mall hallway and this was smack in the middle just outside of the Sears door. I would "assume" that permit holders are allowed to carry in the mall. I did not check any of the main hallway entrances to see if they said different.
Plus, the family and I were headed to the movies in the mall, and I searched all of the windows and doors of the theater and the only sign forbidding anything was the no outside food or drink. So, it appears that GSM is carry friendly.
