Pizza delivered to the Train? Old hat. The best pizza delivery story I have is pizza being delivered to Boy Scouts near Philmont, NM. Several of the treks (ten-day high adventure hikes) cross one of the state highways that bisect the reservation. With the advent of cell phones, well, you get the idea.
The scouts in charge at Philmont Ranch discourage this, and have even co-opted cooperation from most of the pizza outlets (there are only a few) in the area, telling them that they will come off the "recommended" list, of POST-hike places to chow down.
Can't say I blame them, just something "not right" about getting a fresh-n-hot pizza delivered while you are supposed to be in the middle of a ten day "wilderness trek".
Ingenuity coupled with hunger, don'tcha love it?
