Dad/Grandpa's interrment expenses

Dad was not prepared for the expenses involved with interrment upon his death.  Though no one is obligated to assist with the expense involved, many have expressed a desire to help out.  He asked to be cremated and have his ashes interred at the National Cemetery in Sturgis,  SD.  The VA will cover costs at the National Cemetery and he will be afforded full military honors.  However, there is the issue of the cost of cremation.  Any assistance you can provide will be greatly appreciated.  You can donate anonymously if you choose.  Thank you, lets see if we can get this done.  Love you guys.
