"A lot of people have a hard time living out of a suitcase, being on the road constantly in different cities. For us it's just kind of what we do. You do get homesick. I miss my wife, I miss my home, I miss my dogs, I miss my kitchen, which is something I like to do outside of this is cook. You miss the simple things. But when you look at the big picture we get to see a crazy amount of cities and the people we get to meet, all over the world it kind of makes up for it. It makes you realize how lucky you are because it could be gone tomorrow you just never know."
