Pennsylvania is currently drafting proposed regulations to allow hunters to use the atlatl (pronounced at-lad-ul), a small wooden device used to propel a six-foot dart as fast as 80 mph.   It has been suggested that the atlatl was effective for hunting and killing wooly mammoths when those beasts last roamed the Earth!   Pennsylvania hunters are chomping at the bit for the chance to use a prehistoric weapon that requires the hunter to get intimately close to his prey.   There are a handful of states which permit use of the atlatl for hunting but one which allows it as well as spears notes that spear hunters outnumber atlatl hunters.   I suppose it is an acquired taste since it obviously makes hunting into a far more sporting ordeal.
