The newest anchor store at the Three Rivers Mall holds a Grand Opening ceremony tomorrow. Sportsman’s Warehouse officially opens its seventh outlet in Washington state at 9 am tomorrow morning at the Three Rivers Mall in Kelso. Special deals and demonstrations are planned through the day, and the first 300 families through the front door will receive a special ball cap and a 20-dollar gift card. The Beretta “Big Rig” trailer will be on hand, with more than 30 firearms on display; there will also be other vendor displays, with gift cards being awarded with qualifying purchases.
