There is a corner in Golden where gluten does not exist. In this gluten-free utopia (glutopia?), the sun shines brighter, the mountains rise higher, the sky burns a few shades bluer. It’s a downright bucolic wonderland for the wheat-free set. A regular Xanagluten-free. Its residents, Holidaily Brewing Company and its small posse of gluten-free food trucks, are a happy, peppy sort of people.
