Johnny says he's came across a new site that has "40 Maps that will help you make sense of the world.". He's also found a great app for shopping while traveling. It's called Savvy Traveler's Simply Declare, which allows you to keep track of your purchases so when you have to declare them on the way home, you can accurately do so.
Johnny also says to bring some wipes and wipe down everything before you sit down on your flight, even the handles for the overhead bin. Most people get sick when they fly and it's because airplanes are petri dishes. Doctor Mom says that wipes are useless though. It's important to constantly wash your hands while traveling, which will also help.
Lastly, Johnny has a new webpage on his website that allows you to check out alternate airports when you travel to save money.
