for a bear bag, I use a cheap thin bag with strings so I can use it as a backpack. I then take a log attached to a rope and throw like a javelin. Works every almost everytime. I some times will have no trees at all I put all my food under my tent and practiced the piss method.
In 74 days nothing ever touched my food. I wonder about hunting style. Say if I am there only for 8 hours will my chances of seeing a bear increase I think this plays into it also. In that time I had several occasions were I camped for days I know they were out there just never bothered me. One time I left my chicken out for them and it was gone in an hour.
I had animals come up to my tent, I just shooed them away. Another trick is I put my food under my trailer and covered it. I would come back from two days of hiking and it was still there.
Not to say you or I will have the same adventure. I rarely ate at my sleeping site if I was hungry I would go for a walk and have a picnic.
Use a stream to keep your item cool.
Buy milk the previous day and drink it after it cools overnight.
Most refigerated items can go days with out power.
Peanut butter and flour tortillas.
Apircots
Look for water bieng more expensive than pop. Simply buy pop drink and refill with water.
Use pop bottles to steep oatmeal plus water to rinse throw away after done.
Buy half gallon milk jugs Chop of the top but leave the one side not cut make a handle with a bowl throw away.
buy tupperware from dollar stores
Camp soap no hot water needed. biodegradable
Raw diet no camp stove of fuel needed. Microwave at nearest city.
I like 40 upfront and 60 back. Especially where on the road the front can slide on you.
Also if I have a flat tire I might take the load off.
Buy a shearer valve adapter so you can use the gas station air. .
Take a picture of a map so you can view it latter you can even zoom in
Buy a trailer so you don't get stuck buying expensive food.
I cycled for 5 days till my first food store. Ate like a king the whole time. I then spent another 5 in the forest after replenishing some items.
Ship it back home through greyhound about a buck per pound. Should have a BOB box also.
Better yet Set up care packages for you then find buddy to drop them in the mail. Pick them up at the US post office via general delivery. I thin everyone could use a tube tire box. You could even send a duffel back or suit case for your bike. I met a person on tour who would get food sent to him.
Search forums or boards and or meet up with people along your tour.
Look for visitor centers or ranger stations prune at will. All of the ones I went to could list sources of water for a hundred miles. Some were described as a church spicket with clean water.
I stopped at a ranger station in Silverthrone CO which are everywhere CO, for the usual restroom, cool water, and a place to sleep in their nice forest or wilderness. Come out and changed my route to ride on the bike path after she suggested a ride to Vail. Best 400 miles I could have ever imagined.
Bring water tablets to filter
A whistle light weight and powerful
Most libraries have gazetteers (maps) where all the free camping is. To be honest I never carried a map I just took pictures of the map and used bikely to plan as I went.
