I posted the slots still available as a followup to the Unused Permits 2017 post.

Deke: Welcome. Your options: snag a permit from the available slots Apr 1 at 7 AM (Pacific) from those still left.

Also, if anyone declines their slots before Apr 1 (not sure if they can), those will come available on Apr 1, but at random times.

During all of April, if anyone declines their slots, they will show up randomly in the next 24 hours.

On May 1, slots that winners have not paid for will show up as available, again at a random time, throughout the day.
