I did send way too much to the AT in maildrops in '89: about every 200 miles. As a vegan healthfooder, you almost have to send half of your food to trail. Oatmeal, bread, chips, & other supermarket staples can easily be bought along the trail (sandwiches were my usual lunch; just keep whole wheat bread & chips in top part of your pack). On PCT I had maildrops about every 300 miles & separated half the drop to forward about 8-10 days ahead(only send priority if PO might be closed, you can drop em a postcard or call to forward for free). On the CDT, I did most of my own shopping at Health food stores etc… (Bozeman MT, Denver,CO et al)… I used drift boxes to supplement what I knew I could get in trail towns, becuz I had bicycled down the Rockies after a failed CDT 03 attempt which got me really ready for my CDT/RMT '04. I was surprised how much veg healthfood I could get in towns like E.Glacier (few soy products), Butte(Walmart) Lander, Rawlins, W.Yellowstone, Colorado ski towns (healthfoodshops)
as well as in Silver City & Chama. If you don’t like cancercausing chemicals in your food, you will have to buy instant soup from the bulk section of hfstores & some supermarkets. I also used powdered soymilk, cookies & chocolate bars with evaporated cane juice as sweetener, which in my experience doesn’t affect your performance like bleached, devitaminized, demineralized white sugar seems to me to do. I carried non-hydrogenated margarine in a peanut butter jar in a freezer ziploc just in case… liquids like olive oil & booze only work in small soda bottles which often you can find on trail. (PS. don’t mail booze or other flammables).
