I would not call fall collecting "perfect". One of the problems with fall collecting is that, in that zone (6 I think), you have to protect newly collected trees from extreme cold, or you can loose them. It's just a hassle IMO. I have done it in areas where there will be to much snow in the spring. Spring is actually a better time and doing it right when trees are budding out. Once you see buds coming and green showing, get with it. Once they start pushing growth, they will just keep going if collected correctly.
You say you're moving. Moving from the Boise area? Nice area but getting very crowded and expensive.
