Is your question about where she should live or where you should visit?
Trying to be delicate... areas east and north of Downtown Knoxville nside the city are often questionable or bad... crime wise
look hereYour sister has my phone number... or PM me for it if you'd like. There is no place in the area that I mentioned that I'd park my camper over night,
The camping world is about where the high crime starts to taper off. East town mall is not far away from the Camping World and I don't know a single person that would shop there. Not worth the risk based on past news reports.
This is as honest as I can get in print... and I'm still trying to not slander....
Outside the area mentioned is very nice.. more than a dozen stae parks nearby.
(I live about 30 minutes from there
