As mentioned you may want to volunteer at events for this season as it is a little late in the game to get a team started, certainly not impossible but a uphill battle. However now would be a good time to lay the ground work so you can get the people associated with the potential school or organization to an event as that is the best way to hook people. There may also be a team that is interested or in the process of considering a team. The best thing to get plugged into the system is to contact the FIRST Senior Mentor for your area. You can get their contact info here:
http://www.usfirst.org/regional-contacts Now I'm not sure where the line is drawn between the FSM for Northern and Central CA is so you may want to contact them. They may already be working with someone near you to get a team started and if the FSM can say I've got a mentor with experience that is willing to help out that may be enough to encourage them to go through with it. They can also link you in to volunteering for all of the programs. We are stressing the Progression of Programs more than ever so getting hooked up with a FLL or FTC team near you could lead to being able to show the demand for a FRC team when those students are moving on.
