We ended up pulling engines off the Kenai, off of the Matsu area, and Fairbanks all collapsed into this area to start helping to pick that up. As it happened throughout the night, they started right in this area in here, started moving forward. Every time they got where they were starting to get close to getting something happen, a wind would come in, a pulse would hit them, they'd have to pull back out. It was too hot for them to stay in there. They'd pull back out, move down to the next road, try to get re-engaged, kept pushing them over until we ended up where we are now.
