Yep. I'm from here and have some allergies. However, when I did an 8 year stint in Utah and Cali, I had zero issues.

Same here. Raised in Oklahoma, asthmatic with allergies since I was born. Moved to Alaska and it struck me about day #8 that I could actually breathe the air without any kind of distress. Came back here and within a month it was back to the same old struggle.
