The Iowa DNR is trying to get legislation passed to RESTRICT this! They don't want cities (for some reason Iowa City comes to mind, due to their refusal to allow hunting yet hiring White Buffalo as sharp shooters) and private citizens taking matters into their own hands. I hope they ban this, because I sure don't want to eat a deer that has been shot up with some experimental pharmaceutical. If this ever comes about, the DNR wants complete control over the who, what, where, when and why.
