Utah Alcohol Regulations

[socal]

In Pennsylvania you still can’t buy more than 192 ounces of beer (aka roughly two six-packs) at a time.

Huh? I lived in PA for 20 years growing up. They sell Kegs, cases, 30 packs, etc.

That's because PA, as one of the 17 control states, has as confusing a set of laws as many others, including Utah.
In short, it depends where you purchase the beer.
From Wikipedia:

Beer may only be purchased from a restaurant, bar, licensed beer store, or distributor. Beer distributors mainly sell kegs of beer and cases. A beer distributor is also allowed to sell any package intended for resale by a PLCB-approved brewery containing any variety of bottle/can arrangements greater than or equal to 128 ounces. Six and twelve packs, along with individual bottles such as 40 ounce or 24 ounce beers, are sold at bars, restaurants, and licensed retailers. A license granted to a bar or restaurant permits the licensee to sell up to 192 fluid ounces of beer per purchase. For larger quantities one must go to a beverage distributor which sells beer only by the 12-pack, case or keg. Beverage distributors (which also sell soft drinks) may sell beer and malt liquor, but not wine or hard liquor.

Yes, PA does have some weird laws that's for sure. Just wanted to clarify your initial comment wasn't correct. I'd assume in may other states a restaurant or deli can't sell kegs either, maybe I'm wrong though.

Yep, but it really does depend on the state. Part of the dealing to get the 21st amendment passed (repeal of prohibition) was a states rights issue, thus states were allowed to set their own laws regarding alcoholic beverage sales and consumption. As a result we have 53 sets of alcoholic beverage laws:
50 states
federal
military bases
protectorates (Guam, American Samoa, USVI, PR)

A lot of them still include many that were passed in 1933 and now antiquated, rarely if ever enforced, and often downright goofy: bars in Nebraska must have a pot of soup or stew available during operating hours. Some other state (I forget) prohibits allowing your horse to drink beer.
