My first tour was more than 50 years ago, the epic, around the world. About 10 years ago I did a bit in South America.
Alas, I'm not 20 anymore. I have a lot of bits and pieces that one would need if one were going to tour: Panniers, racks, kerosene stove, tents, tires, and I don't know what else.
I am in Carlsbad CA (North San Diego county). So if you don't have an infinite budget for touring, come on by.
Quite frankly, you don't need much more than a will-to-go to tour. I encountered a couple guys touring on unicycles. I met a guy that rode an old Chinese bike from Mumbai to Sri Lanka. I told a buddy about an interview I had where the reporter asked, "How much does it cost to tour?", to which I replied, "I could go around the world on US$5." My buddy said, "What would you do with the change?"
