Oh my gosh!
THANK YOU, loyal_stranger. I have been so busy i forgot to start a thread on this year's 2017 Hoodoo Heritage Festival -- well, better now than never
First, to reply to your questions --
This thread (and the Facebook page for the 2017) are good places to post about your interest in a lodging roommate. We cannot oversee such arrangements of course, but many people do successfully make them. Also, there are AIR Bn'B houses in the area, in addition to hotels and motels.
Best airport? That depends on where you are and the airline you choose. Rest assured that Oakland and San Francisco are about equally distant in terms of driving times in a rental car. The actual "closest" airport is, however, Santa Rosa, as you noticed, and if you want to, you can indeed fly in there; you will still need to arrange transportation to Forestville, however. This is where hooking up with friends comes in handy, as some people go in on a rental car together as well as shared lodging. We are a community, and we really encourage the making of friendships in this realm of shared interest in African American folklore and folk magic.
The Secret Socks will be fun, trust me. Other fun things are on the schedule as well.
Looking forward to seeing you ...
