I am from Ashippun (north of Oconomowoc), but I went to high school in Watertown.
Best suggestion: Stay away from Pick N Save. They don't have a great selection and people don't have a clue if you ask about it. I haven't checked out the Piggly Wiggly there, but I work at the one In Oconomowoc,and there is part of an aisle dedicated to Gluten free, as well as some other stuff scattered around the store.
There is also a store called Back to the Best ( http://www.bestnutrition.org/) that is an organic store run on a family's farm just north of Neosho (east on N off of 67). They carry a brand called Sami's Bakery that is by far better than any store bought bread and are usually made from millet and flax seed.. It isn't guaranteed Gluten free just because of a chance of contact during production, but ingredients-wise it is Gluten and dairy free. The bread comes in all different flavors and also different forms (rolls, tortillas, bagels, etc). If you make it there, definitley get the cinnamon raisin bagels. They're phenomenal and almost addicting.
This also goes for anyone wanting tortillas. This brand has them, and they a a bit more crumbly than normal flour tortillas, but taste better. Rolls too!
I don't have a recipe for bread itself, but for us further out this store is a better option than the loaves from the grocery store. (Better tasting too!)
