An update from my post of January 7, 2009 [Not the Most Fun - Filled Day I've Ever Had. ]:
As it turned out, water was sucked up into the engine via the exhaust.....destroying the engine.
The accident was covered under the insurance and the company subsequently "totaled" the van.
I took one last photo after we cleaned out our personal possessions before the insurance company picked it up from the auto repair place.
