FYI, the National Park Service (NPS) website has been updated to reflect the new law, effective 22-FEB-2010, allowing firearms in NPS properties if and as allowed by state laws.
Here's a nice brochure in PDF format that gives an overall summary of how the new law affects carry options:

And the sub-websites for most NPS properties now contain a little blurb about the law, usually in the "Management" section. For example, here's the page for Carlsbad Caverns in New Mexico:
