I just had to be sure how much Marks traveled this past season, so I found the facts on the admirable @BillV99's website,

Looks as if he made a grand total of 4 trips where he "traveled" that was more than a day trip: Florida last winter, an early season trip to Texas/Missouri, and twice to Knoxville including The Nationals. Pretty limited. He made almost all of his money in Pennsylvania and states that adjoin it. So, not a ton of expenses related to travel.
