What the heck? Why can't you transport firewood? How else do you get it from the wood lot to your house? How is cache camo supposed to be firewood, anyway?
Personally, I don't believe in laws that could never be enforced, but I'd love to take a read of that one.
We have some DNR regulations regarding firewood-no laws yet. From what I read it has to do with an invasive insect - found mainly in Michigan and Ohio. I found this from Maryland DNR.
