Earlier this week we had a spirited discussion of whether the National Park Service needs to add a site to honor Cesar Chavez, who orchestrated the farm labor movement in the 1960s. That discussion nips at a larger question: Has Congress led the Park Service astray and turned it into a catchall agency?

Though few people seem to know or care, Michigan's long-ago abolished Mackinac National Park was America's second national park. Yellowstone got there first, but not by much.

To help encourage folks to get out and enjoy National Great Outdoors Month in June, a wide array of campgrounds across the country, many close to national parks, are offering a 20 percent discount on camping fees.

Should a site "significant to the life of Cesar Chavez and the farm labor movement in the western United States" be added to the National Park System? The NPS is now seeking your comments, and public meetings on the possibility are being held in six locations in coming days.
