1997 Dodge Dakota Leaking antifreeze

I noticed an antifreeze smell when I got home from work yesterday. I popped the hood open and there was antifreeze all over the front of the engine. I'm assuming that the fan and regular air movement from the drive home spread the antifreeze everywhere. I borrowed a pressure tester and hooked it up. I can't spot the leak, but the bottom of the engine (in front), the crossmember and the fan shroud seem to be especially heavily covered with antifreeze. I will try again tomorrow in the daylight hours and with the truck up on ramps so I will have a better view, but do you have any ideas on what my problem could be? Thank you.
