Moved to Chciago about 10 years ago in small part to escape the summer sweat in NC. The first few winters were seemed brutal, and the summers pleasant. Past few years have changed: hot summers and mild winters. It's almost downright pleasant during the past several winter seasons. My snow shovel hasn't been getting much use and was wondering if it was all in my imagination.
