I've read good things about Pittsburgh too. But it's a good idea to rent thru a winter first. Having lived in Ohio and Indiana for 29 years of my life, about the same latitude, winters can be awful. Annual snowfall for Pittsburgh is about 30 inches, some years will be less, but some more. A white Christmas is nice, but after that it gets old really fast. By March or sooner every winter I often ask myself 'why the hell do we live here?'
Summers can get warm too, but it's relatively nice here during summer. We had two days last week with high's below 80F, wonderful. And I spent years 3 years in Dallas and 4 in San Antonio so I know Texas weather. Texas has been brutally hot and dry (water restrictions?) this year.
After extensive research I have found the city with the best climate in the USA, it's Santa Barbara CA. Too bad the cost of living, politics, etc. are beyond my tolerance for pain.
