Hundreds are expected to turn out at noon Saturday in Niagara Square for a “Gun Appreciation Day” rally organized locally by New York Tea Party leader Rus Thompson.

“What started out as a small thing is absolutely exploding,” Thompson said.

Close to 700 people already had agreed to come to the rally as of Thursday morning, according to the event’s Facebook page.

The rally is one of an array of events being organized nationwide Saturday in support of the Second Amendment.

Participants are being asked to “bring the Stars and Stripes and pro Second Amendment signs,” the invitation on Facebook reads.

“Lets show our government that we won’t tolerate our rights being infringed upon,” it continued.
