All I have to say it get out while you can and don't look back!
We just moved to Sheridan, WY from Oregon, about an hour from Portland area..
My husband is actually in the HVAC trade

he actually got a raise by moving here.. and is treated with a lot more respect and dignity as well.. So we are happy campers..
Sheridan is next to the Big Horn Mountains, which are beautiful..
As far as more trees, I think that Story, WY, not to far from here has more trees than in Sheridan, really anywhere in Wyoming is not going to look like OR and be as green. But we were willing to give up that in order the live in a different surrounding and lifestyle.
Buffalo has a little bit more trees than here I think? My husband has gone there for some jobs, I haven't personally, but that is what he tells me.. Although I think Sheridan is a pretty place and I love it here so far..
Best of luck to you, if you can't find someone to buy your business, I bet that Roth heating out of Canby, OR a great big company and growing would want to buy your business.. I don't personally care for their company, but they buy a lot of little shops and use them as "sattelite shops"
Best of luck to you and your family..
