I think the only time you can't buy liquor in Iowa is in the dead of morning -- 2 a.m. to 6 a.m.. That's probably to give the bars assistance in getting the drunks to leave. Sunday sales do require a separate permit -- gotta maximize those revenues. And yes, the alcohol is in a separate area in Wally World -- with doors that close & lock. But our local Hy-Vee has the liquor right in the aisles with other groceries-- I don't think they ever do much business from 2 a.m. to 6 a.m. And Fareway is closed on Sundays and always from 2 a.m. to 6 a.m. so their liquor is with the regular groceries. And we have a specal provision that allows regular Mon-Sat licenses to cover New Year's Eve if it is on a Sunday. But I remember when I was a kid, people used to drive to SDak to buy beer on Sunday.
