I called PETCO in Gillette this morning.
They sell at least one (maybe more) freeze dried. For example, they have Instinct freeze dried. Plus they have frozen (or refrigerated, if I understood them correctly, got like 2 different answers) raw food including Instinct and Fresh Pet.
They don't seem to have Stella and Chewy's or Tucker's frozen raw (2 that we use at home) or Darwin's (which we used to use). They don't seem to have Honest Kitchen, which we use at home also.
Personally, I am bringing Honest Kitchen and Stella and Chewy's freeze dried patties. No hassling with frozen or fresh raw on such a long road trip. I will augment from Petco there if any need be. The Stella and Chewy's patties are expensive, but not so bad if used to augment another item - like Honest Kitchen.
I believe Stella and Chewy's is available online, Maybe Honest Kitchen also.
