Hey Jake,the map you got is good.:) There are a bunch of motels at hwy 12.(if you turn right on hwy 12)right off the freeway.To get to gaurd rd take hwy 5 to hwy 12,turn left on hwy 12.Gaurd rd is up about 1 mile.Turn left( I think there's a sign for gaurd rd)Follow it untile you hit the river and keep going for a little bit.There is a bend in the road with a turn out?I think it's the 2nd one.
If you plan to sleep on the levy please post and me & buzzfish could probably meet ya there.It is out in nomans land and I'm not sure you'ld want to be there alone;( You can always call me on my cell 510-673-5933.:)
