Oregon PMHNP

Hello, I am new to posting here, so I hope this is ok. I was curious as why it seems so many PMHNP all want to practice in Oregon? Is there something about Oregon that makes it better than other states to practice in such as Washington or California? I am on the East coast and it seem like there is so much need here and throughout the country, but the focus is always to find a way to practice in Oregon. Thank you
