After much thought and discussion, I'm pulling out of Autumn Leaves this year.
I haven't been able to keep up my cardio base via cross-training very well due to my limited ability to put solid weight on my foot. I'm getting better, but not fast enough. By the time I can start running again (about 2-3 weeks minimum left), I'm looking at a training time that is WAY TOO SHORT for my own good when it comes to a 50 miler (even one with a generous cutoff time.) So this leaves me with possibly doing the iUWR Marathon this year, but definitely the Seattle Ghost 50k and all races after that day.
I have to say, this is one way NOT to start out training for your first hundred miler.
