I realize that I am reviving an old thread here but I wanted to comment that I picked up a package of the GREN's at Menard's. It was an impulse buy because I was curious how they would do and the normal $5 package was on sale for 3.98 so that's 20% off. Anyway I've burned 3 so far and they seem to burn well and may be great to mix in with marginal wood if you have to. I am keeping the rest of the package dry and indoors with the idea that I could use them in an emergency or if I have damp wood *from rain and snow not unseasoned* Just my two cents if anyone else is looking at these.
