Which is totally dependent on Conditions:
During the fire in Colorado near Fort Collins, which was grass
started, the green growth that was there on the ground was going up in
You have to specify conditions! If you had seen most of the homes
that went up in the Haymane fire in Colorado, you will see a lot
