Not too far from you is the Finger Lakes National Forest ranger station.
Pay them a visit and ask them to show you what they are using for grass, brush and forest fires. Some places need the big 1.5" hose, but we extinguish 90% of the fires with a 3/4" hardline on a reel.
Take a look at the tools, swatters, fire rakes, etc. In many areas in the Eastern Hardwood Forest region, they use backpack leaf blowers to construct fire breaks through the leaves.
Also might check out a NY State forestry station.
Up here, the US Fish & Wildlife Service fire program uses Polaris Ranger 6x6 UTV's with a tank, Honda WX15 pump and small hose on a reel.
Here is a similar unit that is used by a nature conservancy in Wisconsin for holding their fire breaks on prescribed burns.
If you cannot extinguish a spot fire with the Workman, 60 gallon plastic tank, pump and 100' of 3/4" Ag hose with garden hose nozzle, you need to have the Fire Department out there, anyway.
As someone already mentioned, prevention is "key", and I stress the "right" conditions - not just the night of the bonfire, but the extended forecast as well. If the relative humidity is in the thirties, you can get spotting, If the RH is in the 20's, expect to be needing the fire department when the wind comes up.
This is not the forum to try to make you a "burn boss", but take a look at the parameters, below, for burning and remember the 40-60 rule - relative humidity at or above 40% and temperatures at or below 60 degrees and you should be able to handle anything with a garden hose off a sprayer in your neck of the woods (this does not pertain to California, Australia, Pitch pine of east coast, etc.)

The burn article I saw mentioned that spot fires can occur from a large pile, 500 feet away.
When things "green up" in the Spring, the danger is lessened.
Good luck and send photos of the site.
