Yomtov Sheni

B'nei Chu"L who say they can't imagine only having one day of Yomtov are comparable to diplopics who can't imagine ever being cured. HaShem had a reason for decreeing that we celebrate only one day of Yomtov, only eating matzah one night, only sitting in a Sukkah one night, etc. To complain about the potential loss of a day when one makes aliyah sounds very much like one views the chagim in terms of how he himself enjoys them, rather than in terms of the benefit that HaShem desired that we accrue from them.

Is it normal to shecht one's korban pesach but, before roasting it and eating it after nightfall, to go to watch the omer be harvested?
