Let's check out Angel Island! I've been meaning to check it out - let's do it together. This island is a State Park open to the public. There are two ferries that go to the island -- one from Fisherman's Wharf, the other from Tiburon, in Marin County.
The island is small (about 1 square mile) but it's hilly and I've heard there's a lot to see.
Let's meet at the Angel Island Ferry Terminal at noon. It's the only ferry terminal on the island. I'll be waiting until 12:15 but then will be heading out to explore with whoever is there -- I'll be checking my phone for messages, so if you need to contact me morning of (running late), PM me for my phone number. Make sure to wear hiking clothes and to bring plenty of water.
