Travel (much like life in general) often contains elements of grace. Sometimes you give grace, sometimes you receive grace and other times you are just a witness to grace like Kevin in the article linked below. The difference with grace during travel is that as long as you keep your eyes open it is sometimes easier to see. You are no longer in your home element, often times not even in an area where you can speak the local language. You are looking to soak in new sights and new experiences. In those times, you do tend to become more aware of things around you, including grace.
If you are not familiar with who Kevin is, he is the author of Wisconsin’s Best Beer Guide.
