It takes a brisk pace to keep up with John Stone as he ducks in and out of new stores at Riverstone, his live/work/shop/play community built on former industrial land in Coeur d’Alene. Working his way down Main Street toward the 14-screen Regal Cinemas, the developer shows off a hair salon, a nail salon, a tanning business, a sports memorabilia shop and a fitness class space decorated with graffiti-style murals. Across the street, work is nearly done on Bullman’s Wood Fired Pizza, which will bring the number of Riverstone eateries to eight.
