ha! Oh yes I am very familiar with most all of norcal. I traveled through there and spent quite a bit of time in the GV/NC area. Im also quite familar with Pen Valley and the R&R area also. I also lived in Browns Valley/Loma Rica area and spent a bit of time up the Yuba in all the little towns. Oregen House, Camptonville, Downieville, etc. Also the Marysville/Wheatland area, Chico/Paradise area ad the Redbluff, Corning, Redding, Lassen area.
And I have some very close friends that also grew up in R&R. Im sure we have similar aquaintances.
