This is the story of a overnight tour Rowan and I did back in 2006.

We had the bicycles, we had the equipment. But our equipment isn't tremendously expensive ... we've collected decent quality stuff for good prices from many different sources over many years.
I can't remember how much the campground cost, but I'm thinking it was something like $15. I'm pretty sure we had something to eat once we arrived at the campground, and then pancakes for breakfast. That wouldn't have cost us $10 or so. So for approx. $25 we did a tour ... a beautiful, memorable tour.
You don't need to be well off to enjoy touring, you don't need to have lots of time to tour, and you don't need to do something "epic" to have a wonderful touring experience.
