We are considering moving from Las Vegas, NV to Portland, OR and we would like some pros and cons between the two cities. We are in our 30's and have 3 children. We have a nine year old girl, a six year old girl and a two year old boy. My disabled mother also lives with us, she is sixty-nine. We have two small dogs. My oldest daughter and I both have terrible sinus troubles, and since we've moved to Las Vegas, they have gotten out of control! I would also like information for better health for our noses in Portland if available. Links to studies and reports are appreciated. Strong points about where is a better place to raise children and why. Thanks!
