Shooting offered as an extracurricular in some U.S. schools

Trap-shooting is seeing a rise in popularity in Minnesota schools, according to a Bloomberg report.

In just six years, the Minnesota State High School Clay Target League championship has seen its attendance rise by 5,000 people, according to the report.

Despite the uneasiness the public may have about guns in schools, the growth of the sport has yielded good fortunes for both manufacturers and retailers. A young competitor who is aged 16 today is likely to invest $75,000 into the sport over the course of a lifetime, the National Shooting Sports Foundation estimates.

Teams are expected to spend $5 million in competition costs this year, according to a league estimate.

The rise in popularity has not translated into violence.

USA High School Clay Target League founder Jim Sable emphasizes his motto is "safety, fun and marksmanship, in that order." No guns are allowed on campus, and no injuries have been reported at competitions, according to Bloomberg.
