Just a footnote on the BH Ranger Station.  When I was there on May 24, I was going to pay for my park fee using a credit card.  The lady ranger tried to run my credit card, but could not get reception.  She said she tried to get reception at the end of the dock, but was unable to get reception to run the credit card.  I had cash so I paid with cash.  If you plan on using a credit card, you may want to check to confirm if the station can take credit cards.
