Tell them to move to Minnesota
We have more sponsors than high schools. I think were doing something wrong.
My advice? Find a big company w/o a FIRST team and show up at their HQ. Keep asking to see an executive (politely) until you have an appointment. Then be prompt for the meeting and present the FIRST video along with personal stories in addition to explaining the benefits the company will get by sponsoring you (usually "a good feeling" doesn't cut it). Don't accept a "no" without reason (again, ask politely). Learn from that reason, fix it, and try again.
