I drifted them just like you would drift bait, yarn, etc. I run my leader a little longer (a little over 4 feet) and thread it down onto the top of the hook with a worm threader/bait threader. I've had tremendous luck fishing it this way as of late. The winter runs liked it even more than the summer runs. When the waters a little murky those steelies just can't seem to resist it. The second fish had it buried so deep in it's throat that I could barely see the eye of the hook. Oh yeah, put a bead above your hook to protect the worm from sliding over the hook.
Good luck
