My learning partner David noted that things tend to fall apart when one is not in Uman for Rosh Hashana. This year I did not take his advice and in fact right after Rosh Hashana things fell apart. But I am still not thinking of being in Uman since it has become dangerous. Very dangerous. So the best overall idea I think would be to bring the grave to Israel. The problem with that though it it is not known exactly where the actual grave is. One fellow who paints portraits there told me that a WWII survivor told him that she knew the actual site is not where people think but rather North West about ten yards. from the grave site that is marked. [Actually West but slightly north]
