Help rebuild my 83yr old Fathers barn lost in fire

On September 13, 2019 my 83 yr old father and mother abruptly woke up to see their barn fully engulfed in flames.  This picture is my 83yr old father looking at what's left of his barn.  This is where we put our crops in for the last 58 years.  This is the barn where we milked cows to support and raise a family.  This is the barn where we worked and played most of our lives.  Now it is gone and why??  Senselessly with no reason.  A land owner with no barn is a land owner.  A land owner with a barn is a farmer.  Please help me to rebuild my fathers barn.  Unfortunately they were under insured for rebuilding.  To build a barn this size would cost $500,000 or more.  We are planning to try to rebuild this spring and any donation to help achieve this will be greatly appreciated.  Please help show this older couple the love and kindness and that even though something bad has happened, good things can come from it.  Thank you and God Bless.
