They're in Bozeman, Montana...which is a big win for us here in Seattle. A ground shipment from Bozeman only takes a couple days. My recent trial of getting a shipment of rats from Texas took 9 days (with delays, but even if it had been on time they projected 5 days)
I ran across Rodent Barn because, as you might recall, my introduction to ball pythons was a pain in the tail with a young hatchling refusing to eat and hitting the 60g mark. I ended up working quite a bit with not only this forum, but also a snake breeder/seller in Montana who coached me along quite a bit. She used to be the manager at Rodent Barn and passed the info along to me. I have been tremendously pleased with them.
