I'm planning to hike the entire AZT as a through-hike somewhere in March-May next year. I have a few questions regarding food along the trail
1) Is it feasible to trek the AZT with a "buy-as-you-go" approach? I mean without sending resupply boxes and just buying several days food as you pass near villages?
2) Would I be able to buy lightweight dried food like tortellini or ready meals that just needs adding water? Not sure if these things are popular in the USA but in Europe it is common food for students, bachelors and other lazy people

3) If this is not possible (or not preferable), can a store like Wallmart (where you can order food online) send packages with food to postoffices? This may be a stupid question but I don't live in the USA so I have no idea!
4) Are gas cannisters easy or difficult to buy in villages near the trail? I guess in a place like Flagstaff it should be no problem but in smaller places?
Thanks so much!
