Hi Gayle! We are also from PA and relocating to Tega Cay in the next few weeks (if all goes well on our contract here...keeping our fingers crossed!) We have been making trips down and doing research since September and we settled on Tega Cay after visiting several neighborhoods in Fort Mill. We just kept coming back to Tega because of the lake and the landscape and greenery. The trees are beautiful and the city protects them which is an added plus- you can not cut down a tree more then 4 inches in diameter without city approval. Lovesthecarolinas, please correct me if I am misspeaking here...
Baxter is nice also- I don't think you can go wrong in either area! Let me know if I can help at all as someone who is going through the same thing!
