Well, I wish you just the best of luck & I'm excited for you!
I lived there for ten years (college & after) & I loved Greenville. It's the heart of "down east NC". Truthfully, the traffic is awful to me now when I visit, on the main thoroughfares. As a counter to that though, I'm glad they've gained so much more in the way of restaurants/retail than they did when I was there. I'll be really glad when they get large enough for a Pottery Barn, Restoration Hardware, Talbots Kids (versus just Talbots), etc. but I truly feel that will come in the future. They have some great small boutique shopping in Arlington Village--lots for a town their size.
As a sidenote, if you want to fit right in with all the other females around town...be sure to visit Jenni K Jewelry. She's a very, very popular in Greenville (in Arlington Village) & a well known sterling silver jewelry designer...think she has a website too (although it's not great). Her bracelets are a must.
I know I said ECU was a party school, but your family will love the football tailgating...it's quite an event for all ages. Because it's such a college town...the whole place is psyched for games. Purple & Gold everywhere you look--every car in sight sporting flags--all the business signs supporting them. It's very fun & I know your family will enjoy it. Go Pirates!
I'll give you another fun piece of trivia...so you'll be in the know...Greenville is also referred to as "G-Vegas" amongst the college set...another nickname is "The Emerald City".
