Every Fourth of July, one of the original owners, Janne Johnson of the old Holmberg - Johnson Blacksmith and Wagon Shop, would carry two large anvils outside the shop and at 4:30 a.m. place a heavy charge of blasting powder around one anvil, place the other anvil on top, and set the blast off with a long fuse. The explosion could be heard all over town and was the signal to start the July 4th celebration. Today, the shop is the Blacksmith Coffee Roastery dealing a different sort of charge—artisan forged coffee. Specializing in premium, single origin, arabica bean coffees, this micro-roastery on Main Street offers tours, coffee-tastings, and classes in brewing a fabulous cup of coffee.
