Welcome to the California Open Carry forum.
I am not aware of much activity in the Yuba/Sutter area- though I did notice your comment about the Tea Party OC. The availiability of CCW does influence OC activism. However, CCW being taxed, and issued only to those willing to surrender their rights is only a privelege, whereas OC (particularly LOC) is the unfettered Constitutional right.
After the revelation of the SCOTUS decision in June, there will be more activity- at least thats what Im planning. I will be sure to announce in advance.
