I hope their move goes smoothly and they find lots to love in south Florida.
I moved here with my then husband 34 years ago and have never gone back to NJ. I agree, I had a bit of culture shock. There was no theater or concerts in North Florida without traveling to another major city and yes, things do move a little slower here. But those were the only things that struck me as different than living up north. I didn't miss the snow and the freezing cold weather. I can say N. Florida was a great place for my daughter to grow up and she was able to see a lot of her Dad's family. My Mom (born and bred in NJ) also moved down here to live with me to get away from the snow. She loved it here, she stayed for 28 years.
