The most dangerous crop for fires is safflower! We had a field close to us go up when I was groing up.Yes, my apartment overlooked a huge tomato field. Took a lot of self control to not get samples!
One time the field caught fire. Memory is fuzzy, but they must have alternated crops in the field because this was grass fire... 18 inch high dry straw. I heard it before I saw it, lots of crackling. Took the fire dept a long time to get there since Cowell Rd was actually in 2 sections and they weren't sure where to go! Got it out quickly once they got there.
They let it dry out before harvesting and the swather hit a rock causing a spark. Dad made us go onto the roof to hose it down. It worked and the house was fine!
