Exercise your best judgement.  Remember the forest you save likely contains you.   ;)

Judgement goes both ways.  I was once on a trip and after several days of no rain, bone dry ground, wilting greenery we self-imposed a fire ban.

I've had some downpours that seemed like a lot of rain, the rivers certainly gushed.  All of it ran off the surface.  Not even 1/4" on wet ground before I was kicking up dust.

Campfires are nice, but they're luxury.  Some places have ugly steel barrels dug in to the ground.  That's how you know the area is frequented by idiots who want more than they think.
