Get Caleb and Cody to Slovakia

We found out today that Caleb and Cody's father, Tracy, passed away unexpectedly from a heart attack. He was currently residing in Slovakia and the boys would like to go to Slovakia to pay their last respects and claim the body but money is tight. A close family friend has offered t o help but we still need at least $4000 to help cover airfare and traveling expenses. Any amount helps. Thank you.
