Rock, if you can get anyone with a trailer to help you, you should try cutting a load and taking it into a city--it's insane what city dwellers will pay for a load of good oak wood.

As the others have said, oak firewood will last and last if kept dry. It is usually better after 2 or 3 years of drying time. This is a good project as the cost of home heating most likely will not go down in future years, so what gets cut today may well be worth more in a few years, not to mention that this is a good project to help your wife to stay in shape in her spare time.
Properly stored wood will keep for centuries. This winter I'm burning some that is over 230 years old. Nice and dry. It was part of a building we took down. Most of the building we salvaged as parts to use on other projects but there were some scraps and they warm me now.
The key is to keep the wood well up off the ground, covered, dry and well ventilated. In some climates one also has termites and other miscreants to deal with.
One of our farmer neighbors had his property logged about five years ago. Dh noticed the tons of tops left all over the woods and finally, about a year later, asked the farmer what he was going to do with them. The answer: nothing, if you want them, take them!
Every winter we cut some more and leave it in stacks around the woods. It sits usually for a year or two before we bring it in and stack next to our woodboiler. So far we haven't run into any rotted wood and this is stuff left out in the open after cutting. Dh is still cutting tops, all those are in great shape even after laying on the ground for five years.
