It's a small town of around 10k people. Ripley is a safe place. Here are some photos of Ripley and the surrounding county:

Ripley is a quiet town. There's not exactly a lot to do here. Any reasonable entertainment or shopping is at least 45 minutes to one hour away. There are the major fast food places here and around 5 other restaurants that are just okay. Nothing gourmet here, unfortunately. Schools are good and safe. There are many great teachers in the system.
I recommend looking closer to Jackson, TN. That way, you will be closer to modern amenities and shopping. Feel free to ask more!
