Thanks for posting your story. It's one everyone who rides in remote areas should read, especially those who ride heavy bikes alone.
I do a lot of riding in remote areas of eastern Oregon but the bike I usually take weighs 180 lbs so I can lift it over obstacles when necessary. The tool kit has about every possible thing I could possibly need to fix the simple bike, 2 spare tubes, CDI, chain tool, spare section of chain, bike pump, etc.. Always a quart or more of water. Cell phone is useless here too so I usually carry an aviation radio figuring eventually a plane will fly over and I can ask the pilot to contact someone.
