Here in Florida, our growler laws are still out of whack with the rest of the country, and 32oz are the standard, since 64oz or illegal! We ccan have 32 and below... and 1 gallon and above... nothing in between.
Many of us love to collect growlers from breweries - including other states - but can't use them here for fills since they are almost exclusively 64oz.
Just something to think about.
