I lived in Greenville (NW) SC for six years, so I'll try to help you out...
1) What is the weather like? Do you get snow and ice? do you have seasons?
Winter lasts from about November to March. The temp can start in the 30s in the morning, and end up in the 60s by faternoon. I believe it "snowed" twice in the six years I was there, and it amounted to about an inch, and melted by 9am. They do get a few ice storms a year, but they are also short lived.
2) How is pay for RN's working hospitals without BSN?
I was making about $24/hr on nights with 2 yr experience when I left.
3) How are the prices of realestate.
VERY reasonable. My sister bought a 3br/2ba house on a golf course on 1/2 acre of woods for $142k. You can find mini-mansions for $200k.
5) How are the taxes
My sister pays $600/yr in property taxes, and she is in the nicer part of the city. You do pay property tax on your vehicles each year.
4) are there places to bike ride or hike??
Where I lived there were lots of mountains and state parks with trails, waterfalls, etc. The Upstate borders the mountains....they're beautiful, and its much cooler.
5) Any suggestions for nice towns/cities to live?
Greenville, Greer, Simpsonville or any other suburbs of Greenville. www.ghs.org
Greenville Memorial has a childrens hospital, and Spartanburg Regional www.srhs.org
has a great NICU and PICU. St Francis also has several hospitals there. I loved Greenville. I plan on heading back when grad school is over.
Charleston is nice, and is home to MUSC Medical center, but it's expensive, considering salaries.
6) whatever else you would like to add that may be important.
