Sorry to hear you got hit - hopefully the trees were the limit of the damage.
Please, please, please, don't use Gumball (aka Sweetgum) wood to smoke food. I've seen it on several lists of woods to *not* use for food smoking
because you risk making yourself sick. I believe it has something to do with it's high amount of shikimic acid.
It is safe for firewood (although from the sounds of things, burns really quickly after it's been seasoned) - but you don't want to expose food to it.
