Just remember yidden are everywhere - In downtown San Fran and a homeless man in front of Starbucks yells out "Shalom Brotha". I look over my shoulder. Ask where is best to get a cab. He helps me and I give me a $1 ask if he is Jewish and walk away with a lesson for the day. Holy neshama's are everywhere. We don't know their purpose but they are yidden and our family.
Just be respectful - I had to daven on the plane one morning. My friend sent me an email that morning that the same airline called the FBI when frum men davened on the plane. So I walked up to the flight attendants and told them "I need to pray...". I do my thing and before we are suppose to land they all came over to me saying thank you for being so respectful to us. Lets just not forgot a first impression always counts.
While I would have rather been at home with my family, learning in my chabura, and eating my wife's delicious lunches, my travels provided me with a many learnings I could not have grasped from sitting in my daled amos.
We (well I'll speak for myself) often get rapped up in complexity. Keep life simple as the simplest things are more often the most important.
