We got this in our email this morning....and it might help with the concern that a LOT of permits are being reserved, but maybe not used. Hoover has always been a bit simpler in terms of permit--they've allowed you to self register for years at some of their trailheads. This should make things easier:
Important Update for Humboldt-Toiyabe National Forest Wilderness Permits
All Humboldt-Toiyabe Wilderness permits will be available to print at home within 7 days of the entry date. Please check your recreation.gov account as your entry date approaches.
Additionally, the remaining half of our quota will be released online, 3 days in advance of the entry date. These permits will be available to print immediately.
Please print your permits before you make your trip to the Hoover Wilderness. Printing services may not be available in the local area.
Once your permit is printed to PDF no changes can be made. You are responsible for printing and maintaining a hard copy in your possession for the duration of your trip.
Have a great trip!
