Liquor stores in Austin close at 11:00 and are closed on Sundays, the grocery store sales help mitigate some of the access issue but they still have a nightly time restriction and no beer/wine sales before noon on Sunday. To me the liquor store hours are not as big of an issue as refrigeration and grocery store sales.

Ours here in Denver can be open until midnight and on Sunday but many choose to close on Sunday and earlier during the week. We also don't have high point beer or wine in grocery stores.
