Why do the el camino?

Most do the El Camino for spiritual reasons but that isn't the case for Pat and I. We're Catholic but not practicing. To be honest, we're doing it more as an adventure. It might be a test. Really, to spend thirty days, twenty four hours with anyone can be testing. I don't think we have any concerns. The one question that is common along the El Camino is,"why are you doing this"? I hope not to be asked this to often.
