Sadly, in the US, the environmentalists have gotten so many places designated wilderness that the roads which were originally cut for fighting wildfires have been closed off. Yea firefighters cant drive in either how is that for environmental logic? Additionally the amount of deadfall due to the Pine Beatle years ago doesn't allow for the firefighters an easy way out if trouble happens so it to dangerous to fight, most of the time they can only stage and watch it burn. The Mullen fire here a couple years ago was that way, all they could do was fight a few places where they had access and save a few cabins, for months they just sat at the staging area watching the planes try. In addition almost the whole states funding was spent doing nothing because they couldn't do anything.
Its a shame.
