Medical Travel and expenses, my parents need help

My father had a heart attack and hes currently under medical watch for any reoccurring heart attacks. He has to have open heart surgery in the near future. He was at the Mayo clinic in Phoenix AZ however, they moved him to Hope Hospital.

My parents have little money. My mom drives 3 hours to be with him daily. Her car isn't in the best shape, so the constant traveling is taking its toll on the car, and her. We just want to raise enough money to make her travel back and fourth easier - gas, food, repairs is all they really need. My dad has been a hard worker all his life and has helped out a lot of people, same with my mom. Money is starting to get tight.
