I also had interest from Igineering (
www.igineering.com) which teaches children STEM activities (many of which involve Legos).
Hopefully, Branda has reached out. 3DLT said they definitely wanted to be a part. I'm in talks with LPK. They don't know what kind of a booth they should do or if they only want to sponsor yet.
I didn't think about Boy Scout troops. I'll ask around and see if anyone has anything interesting happening.
I'm trying to convince my husband, who's in the Cincinnati Cycle Club, to do a Maker Ride, and let a group ride their bikes out for it.
