I'm giving a presentation on Exploring the SF Bay Don Edwards National Wildlife Refuge. The presentation includes hiking and biking trails, but concentrates on exploring by kayak. I'll be showing some video and stills from past Kayaker's Alliance meetups. NOTE: This is a presentatioon only. Do not bring your kayak. There is insufficient water at the library for paddling, though you can wear a PFD if it will make you more comfortable.
