Disneyland Blackout Dates iCal via Google Calendar (Public)

I have been unable to locate a calendar feed for Disneyland's Annual Passport blackout dates. The blackout dates are listed on Disneyland's Annual Passholder Gateway Page but there are, again, no subscribable, always-up-to-date calendars available on Disney's site. That strikes me as odd each time I have looked.

I did not look before Google removed Public Calendar Search, but I got tired of not having one available on the broader Internet. It's probably out there, but I can't find it. So, I created my own and will probably update them so long as I live in California. The Google Calendar iCal links are below:

• Disneyland Annual Passport Blackout Dates - Southern California Select (160 days available)
• Disneyland Annual Passport Blackout Dates - Southern California (215 days available)
• Disneyland Annual Passport Blackout Dates - Deluxe (315 days available)

For those of you who want to cut-and-paste:
