So the current team I mentor, FRC 4096 - Ctrl-Z is a team sponsored by JCPenney, and is one of the 10 teams in Illinois sponsored by a JCPenney/4-H Partnership. The two organizations have partnered together to sponsor quite a few number of teams in the state.
JCPenney (nationally) has basically committed to trying to open up as many teams (FRC/FTC) where they have a store. However, it took a while for our store to realize who we were. I think the General Manager was going through some issues.
But your best contact would be your local 4-H County Office. Looking at their website, I can't find much on STEM or Robotics. While you may not be able to get it through them, you can always try and talk to your local JCPenney store.
As a side bonus, you can try to work on getting 4-H Connecticut to pump up their STEM and robotics program
Good Luck!
