Change made in my local copy, will pull in later. (I don't manage usanp in general, but do manage California, and I added that line to the .csv file.)
I should also change the entries in both usanp.csv and usanp_con.csv for Crater Road in Haleakalā NP, once I can figure out how to represent the macroned last letter in "Haleakalā" (it comes out as "?" in both .csvs), or if not just replace it with a regular "a".
