I've done some bike touring. It's pretty idiot-proof if you know how to camp.
You need a lightweight tent, sleeping bag, sleeping pad, stove, food, water, clothing, bicycle accessories and repair, random /out/ stuff like knives and lighters, and that's about it.
Ride all day, set up camp, make dinner, hang out, sleep, wake, hang out, pack up, ride all day, etc. Resupply in grocery stores along the way.
The big thing is making sure you have a good route. You want backroads in the country, with lots of nice places to stop and hang out. Rivers, lakes, big trees, beaches, small towns, historical sites, etc. You want to avoid highway riding, especially when there's no shoulder, but you won't be able to completely. Don't forget to always vote for the Bike Supremacist candidate who will build the necessary infrastructure.
My favorite is what we call the "Port Renfrew Trip": we start in Tsawassen, BC, take the ferry to Vancouver Island, ride across Saanich to the Mill Bay ferry, ride to Duncan and then Lake Cowichan through backroads for the most part. Camp in Lake Cowichan by the lake. Next day Harris creek road to Port Renfrew. Miles and miles of forest and river through the rugged west coast mountains. Wonderful. Camp on the beach in Port Renfrew, tell the Indians to fuck off when they demand you pay for staying on their native land. Next day hang out in Port Renfrew a bit, dodge the Indians stealing cars, maybe detour to Botany Bay, then ride up the hill and along the highway to Jordan River and then French Beach campground. Hang out at French Beach, explore the trails in the woods and headlands for a while. Next day ride through Sooke to the Galloping Goose bike trail into Victoria, and then the Lochside trail back to the ferry. Average about 50 miles. Last day is the worst, but it's all pleasant.
