Thinking about relocating to Denver Colorado?

My wife and I live in Long Island New York with our 8 month old daughter and are thinking about moving to Denver Colorodo. We recently visited Denver for 8 days and we both loved it. My companys headquarters is based in Denver, co I could easily transfer to a position in Denver. We were looking in the Parker, Highlands ranch area for homes. Were are looking for a better quality of life for our family. We would appreciate any Pro's and Con's from people about living in Denver. Thanks
