Add layer from one datar frame to others in same .mxd

I need to write a script that adds the parks layer from the parks data frame in the Austin_TX.mxd (attached)to the other two data frames in the same map document.

Any help would be greatly appreciated. I know this is a very easy script, but I cant seem to wrap my mind around doing it.
