...most likely problem? I can't even find any hot wires in the dash that could be doing it
 
Ya if it did not happen before it could just be a bad battery.

To find what the draw is hook a light bulb between one of the battery and one of the terminals. For a small load something like a brake light would be fine. For a large draw something like a headlight. You wont be able to see something like a headlight glow for a small load. If the load is too big for a small light it will just burn out. You unhook the ground from the battery then use something like jumper cables to connect the bulb in between. Say the red cable goes to the - of the battery and the black goes to the - cable or to any metal part of the car. The other end of the cables is where you hook the bulb. If there is a draw the lamp will glow. The larger the load the brighter it will glow. What you then do is start removing fuses till the light goes off. The fuse that makes the light go off is the one that has the draw on it.

Make sure all lights are off and make sure all doors are securely shut.
If that doesn't work check the lines to the battery for any frays or any white crust on the connectors.
