Q. When one goes to the cemetery to take part in a Matzeva unveiling, if he arrived early, can he first visit the Kever of his relatives buried nearby?
If he walked by the Kever of his parents on the way to the unveiling, can he still go after. since it says that one should not visit a Kever twice in the same day?
A. Horav Shlomo Miller's Shlit'a opinion is that if one has enough time to visit Kever Avos first, he can do so and then join the Hakomas Hamatzeva.
Although it is correct that Poskim write that one should not visit the same Kever twice in one day, (Tzavoas R' Yehuda HeChosid 12, Magen Avrohom 581: 16), Horav Shlomo Miller's Shlit'a opinion is that just walking by is not considered visiting.
