Park & FWS proposed rules for firearm carry
Here, in pdf. The Admin Procedure Act specifies that an agency must propose a rule, allow a reasonable time for comment, and then publish a final rulemaking, in the process doing a reasonable of replying to comments.
Basically, carrying is now forbidden in most National Parks and at least restricted on wildlife refuges. Under this rule, a person could carry concealed (only), if he or she had a CCW permit, and state law permits carrying in state parks or wildlife refuge-like areas.

UPDATE: here's a press release in opposition. Sounds as if they didn't read the proposed rule. E.g., they complain that people might carry in visitor centers, when the proposed rule excludes Park facilities. One of the entities signing onto the release, the Coalition of National Park Service Retirees, states that it has "nearly 650 members," the others give no figures.
