I bet! Wow! Not much is scarier than a grass fire. Your account reminds me very much of the scene in Little House on the Prairie where Laura helps Ma and Pa do the backburn against a prairie fire.
You know, I keep trying to put a time on the whole event...I can't. It seemed like forever we were working on putting it out and it occured to me at one point that we weren't going to be able to and that we needed to call the fire department!
Then Steve got that cardboard (which was very big...as big as the floorpan of a Beetle) and it was wet and even had chunks of ice on it and started slamming that down on it and that took care of it.
