Water leak to passenger side AND driver side

[dogsridewith]

There are few cars on the road that didn't come with one of those drain hoses, aimed at the pavement somewhere in the vicinity of the lower firewall.
I put a small clear plastic bag on the end of my Corolla's recently to help determine coolant use was not a leaky heater core or something else in the airbox. (Sure enough, head gasket...another story.)
