For a few minutes on the first day of Sukkot, we thought that my Artscroll Sukkot machzor was lost (it was found five minutes later in the Sukkah).
Got me thinking though: will I ever be needing this machzor again? Next year, God willing, I will be living in Eretz Yisrael for all of the chagim. As such, I will only be celbrating one day of Yom Tov (instead of two) for Pesach, Shavuot and Sukkot. The Artscroll Sukkot machzor, though very helpful, is very exile-centric. All of the sections on for Yom Tov prayers are assuming that you will be having two days of Yom Tov. And that Chol Hamoed will start on the third day of Sukkot (as opposed to when it really starts, on the second day). Similar confusion with Torah readings and hoshanot.
So I guess I will have to buy a new set of Yom Tov machzorim when I get There. Just one more unpublished aliyah expense (but one I will be happy to pay.
