From: Redding CA, or on a fire somewhere
407 too

why ping pong balls instead of drip torch ??
We have both at our disposal as can been seen in the previous pictures. The particular piece we burnt off was to hold the fire to the South. There was a lot of dead and down in the unit, and we had made an initial decision to not burn that day. Then with about 2 hours of daylight left, the conditions became perfect for a burnout....this was on a Sunday, and did not have a fuel truck close by with gas and diesel, but due to the fuel type, we figured it would work with the balls... As it turned out, the balls worked just fine, we got a head fire ripping along the slope and were able to slow it down and stop it with a saw line, that we black lined by hand, wetted down with the crane and thickened with two lines of balls.

In this next pic, you can see the main head fire on the left, and our holding line just taking on the right with the crane about to wet line and hold it. The two fires sucked in and surprisingly, it held on the ridge top.



My guess is that most people have no clue what I just explained.....But it was a near perfect burnout.
