I don't really have many forests around me, so there's not much need for a forest fire go bag. But if I did have a bag for that, I'd probably put some water in it in case I caught on fire. And maybe a fire extinguisher.
I think you should move to where there is more water and less old, dry, dying trees. Not only would there be less of a chance of fire, but you can jump into the refreshing lake or ocean and cool off in these hot summer months! Then, you can go to the local ice cream shop and eat your favorite cone or sundae!
Swimming and ice cream! What a perfect summer combo! That's what i would put in my go bag!
