Help me get to mom & dad

Both of my parents were in a terrible accident while on vacation in Pittsburg, visiting their youngest grandchild. They were struck as pedestrians in a crosswalk by a coal truck in a busy intersection. They were life-flighted to Allegheny General Hospital in Pittsburg. I live in Maine and will be making trips down to visit with them as often as I can to keep dad smiling, be close to my mother, and to support my sister's family. My dad lost half of his foot, has ribs broken off along his spine, and a head injury. My mom sufferd a head injury so severe they had to remove part of her brain to keep her alive. My mom fractured ribs, a fractured neck, and a broken wrist. She is responsive at times and squeezes our hands when she's awak, which isn't often. Please help me to be with them in between spening time with my own family back home who are also in shock following this tragic accident.
