1911_Guy...they're both fantastic beers!...some of the best tasting stuff I've ever found. 312 has a little bit more of a "kick" to it. You can definately tell it's not your typical domestic beer.
When I was in Chicago, I could find both at the local grocery store, but now that I've moved back to Southern IL, I have to drive to a speciality liquor store, 30 min away, to find either.
I went cheap, this past weekend...a friend had a party at his house (well, it was me, him and 5 girls...good party!), on Sat night...and I put back an 18 pack+ of Miller Light cans, by myself. lol!
