What is the current flowing (and in what direction) in the bottom wire immediately below the current source?

If you have studied current dividers, that should be enough of a hint.

If not, then can you see how to combine the two left-hand resistors into a single effective resistance and use the answer to my earlier question to determine the voltage across both of them?
