Getting nowhere fast

I had another weekly OB appt today, and I learned that I will likely "shoot right past" my due date... I apparently haven't started dilating or effacing, so it looks like Mia's awfully comfortable and not trying to go anywhere soon. But the reason I was dreading getting to this part of the routine is that I could still go into labor tomorrow. And even if I'd dilated a couple of centimeters, labor could still be weeks away. But I now have something else to fixate on, which is probably the last thing I need! So how about a blog pool (sort of like an office pool, but w/o the office...or the cool cash prize) to guess the correct due date? My mom threw out 9/21 as a date b/c my sister and I were both ten days late. Jeff's new guess is 9/20. I'm gonna throw out 9/15, just to be hopeful. ;o) Any other guesses??
