A married couple from Iowa who produce a TV show for the Outdoor Channel have become the latest gun rights advocates to announce they will boycott the Eastern Sports & Outdoor Show.

Lee and Tiffany Lakosky, hosts of "The Crush" hunting and outdoor show, said they won't attend next month's event at the state Farm Show Complex because its organizers have banned the sale and display of assault rifles and high-capacity ammunition magazines.

In a statement, Lee Lakosky said it was a “hard decision” for him and his wife to boycott the Harrisburg show, “but we can’t support a show that doesn’t completely support the Second Amendment.”

Outdoor sporting gear retailing giant Cabela’s Inc. and other smaller firms also have announced they won’t participate in next month’s show because of the ban by its organizers.

The ban comes a month after an armed man shot and killed 26 people, most of them children, at the Sandy Hook Elementary School in Connecticut.

President Obama also is calling for a ban on the sale of assault rifles and high-capacity magazines in the wake of the school massacre, a stance that is causing a sharp public debate.

The Harrisburg show bills itself as the largest outdoor show in the Northeast. More than 1,200 vendors of hunting, fishing, boating, archery and other gear are the roster for the Feb. 2 to 10 event.

A "Boycott the Eastern Sports and Outdoor Show page on Facebook encouraging vendors to withdraw from the show has generated more than 5,300 "likes."

One website calling for a boycott listed more than 50 vendors that have decided to withdraw from the show.

An attempt to obtain comment from Reed Exhibitions, the United Kingdom-based organizer of the show, wasn't immediately successfully. The Harrisburg show is among more than 500 events the firm organizes worldwide covering a wide array of topics.
