I would suggest that the government of the state of Utah may at least develop a plan for some new and ongoing Public Service Announcements, to address the concerns of the matter to the public, before any more controversial measures could ever be taken to more serious consideration for civil discussion and possible legislation, in the state.
It seems to stand to reason that the fires could have all been prevented, if the individual recreational shooters having started each respective fire would've been aware of the additional dangers posed when discharging firearms in a dangerously dry climate, and would've been aware that they were in a dangerously dry climate, and moreover if they would've been personally responsible enough to then avoid discharging their firearms in that climate - and if they would feel they must get some firearms practice, nonetheless, then to use use controlled ranges, as the state had so wisely suggested.
I'd say it could be more effectual for the state to suggest to individual gun owners and gun enthusiasts in Utah they must all exercise their own respective senses of knowledge and personal responsibility, more effectively - and for the state to perhaps set the example, as such - to the point of preventing those wildfires, specifically. I think that that should be far more effectual than any too impassioned arguments, in regards to the many popular concerns of the matter, in the overall democratic climate of the state and the broader nation.
That's my two cents, just thinking to the broader scope of the matter - erm, so to speak.
