I do not understand this. Is there no one west of the Mississippi who knows how to put things into a tortilla?The fresh wraps, etc. have a short shelf life and can't take a western LD roundtrip...it's apparently only good for the 3 day r/t to Miami on the Star. On the other one-night trains, not a bad idea, though.
Amtrak seems to treat mid-route (or, apparently, far-end-of-route) restocking as some sort of highly technical maneuver that necessarily involves gravitational slingshots and wizard spells.
Somewhere in Seattle, there is a business which can deliver an assortment of fresh-baked pastries, salads and sandwiches to the trackside reliably by 4:30pm every day. Amtrak travels through a number of cities en-route, each of which I guarantee you has a business which can provide restocks of fresh food. Why can't Amtrak hire them to do so?
