The old question of Bucket or Belly Tank continues as both systems mature and improve.
Used to be Belly Tanks were used for brush fires and Buckets for Forest Fires.
Then....the Greeners in California who worry about some fish while the whole forest around them is burning down...got into the act.
Their worry....some fire retardant left in on the insides of the bucket might contaminate a bit of water!
Like the mud slides, ash, and fallen timber clogging the very same streams would not create a problem that far transcends any possible contamination done by a bucket.

Forest practices (or the lack of it )also plays a huge role in these fires.
Building Codes that allow for wood shingle roofing and brush/trees being left to grow right up against dwellings and other structures also causes a problem.
Of course....the Media and others shall invariably blame Climate Change for these calamities....rather than fairly discuss ALL the issues that are a factor.
