Anyone signed up to share at The Moth Story Slam recently? How crowded was it?

Curious if anyone knows how difficult it is to get a spot on stage? If there's going to be 50 people competing for 10 spots, I don't know if it'll be worth the drive from Dallas. Dallas has some open mics, but I would prefer The Moth (and wouldn't mind partaking of some fine Houston cuisine while I'm at it)
