You know something--be it a chain restaurant or a fashion trend--has really taken off when you find it in Nampa. No diss on Nampa, it's just that the Canyon County city isn't typically known for being on the cutting edge of much--downtown boutiques aside. But Crossfit--in spite of the fact that it's still somewhat unknown even among gym rats--is now in Nampa. And Meridian. There's also two Crossfit boxes in Eagle and two in Boise. The box is hot, for sure.
