Until they made Carl walk the plank, Carl's Jr and In-N-Out were more alike than not.
The In-N-Out rule is that no store can be more than 600 miles from a company-owned distribution center. They never freeze and do not use restaurant vendors like Sysco. The Lathrop center is 625 miles from Tualitin, so either In-N-Out is going to bend a rule or there's a distribution center going into the Portland Metro that I don't know about.
Anything north of Portland, though, will absolutely need a new distribution center. One in the Portland Metro would be able to serve Seattle, Spokane and Boise.
