Crossbows are looming in the background. For years, states typically permitted crossbows only for those who were physically unable to draw a conventional bow. That’s changing. Thirteen states now allow crossbows during archery seasons. The first, Ohio, permitted them during the last two weeks of the traditional archery season starting in 1976. The number of days was gradually expanded until, in 1982, they were allowed for the entire deer season. Thousands of hunters took advantage of the longer season—so many, in fact, that crossbow hunters now outnumber those who use conventional archery equipment, 140,000 to 110,000 as of 2004. Participation has increased in other states that more recently allowed crossbows, too.
