sorry for the joking in poor taste about BLUE- but you know me..

I've read that BLUE was used about 1/3 as much as ORANGE, but have no idea if it's a PCB/DIOXIN-based herbicide..or what the devil else it may be... toxic to humans??

I'll search for info and pass it along, although
it's more than likely someone else here is 'WAY ahead of me on this.
