Part of the problem is that people built next to the logging areas since they're so quiet and pretty with relatively good roads. That really makes it hard to do controlled burns. And people moved there for the trees so they don't want you to cut them down.

There have been big fires in Oregon and Washington in recent years as well, not just in California. And the Tillamook Burn was big, but that was a long time ago.
I take it you haven't spent much time out in the sticks of Oregon or Washington.
Look at a map of northern California and you see that the landscape is dominated by a checkerboard pattern of logging/no-logging (the most efficient way to maintain a forest and create firebreaks, even if that wasn't the original intent and people are trying their damndest to break the system).
