UPDATE - March 14th, 2017
I spoke to the National Park Service yesterday and the comments have been pouring in at a rate of over 1,000 an hour.
As of yesterday, we passed 100,000 comments total,
As a result, the NPS has extended the comment deadline until April 28th.
To everyone who helped out, thank you so much.
FAQ & Further Reading
Why 50,000 comments? That seems rather arbitrary.
The Department of the Interior uses social pressure to gauge public interest in a project. The National Wildlife Federation has done multiple campaigns similar to this one, and they estimated that 50k comments is the amount it would take for this program to get on the DOI's radar.
I want more information about the Grizzly Bear Restoration Program.
