Coolant leak

[Blast7]

I have a coolant leak and I wanted to get some ideas of where it might be. I am pretty sure it is leaking at the back of the engine because it is very wet back there, but I really haven't had the weather to check it out. I afraid that it might be one of those coolant lines near the firewall that I hear are so difficult to replace. I want to get it taken care of before the weather gets warmer.

Those are the hoses to and from the heater core and there are portions that aren't too tough to get to. Just check it out.
