In all my expience with drinking with americans it has made me very sad. Never have I had a "good" american beer. Not only that, the americans I've drank with can't keep up at all. Most recent example. I was in Bay City Michigan for 3 days partying as part of my drive across Canada/some of USA. Now I brought with me 2 flats of Cold shots.
Note: Cold shots are 250ml cans of 6% beer (the size of a redbull) that you shotgun. Now I let our american friends try some of these. They were all fair sized guys and went on about how much lolrolling rock they could drink. Well one guy had 3 and was trashed beyond belief. and another guy had 5 and was passed out. I think they both might of had 2 lolrolling rocks before I gave them real beer.
On a good night I can shotgun about 10 of these in 20-30 minutes and still be functional. Im drunk no doubt but no where near the pass out/total fubar stage of drinking. That stage is at about 15-18 Cold shots or 14 shots of good ole 151.
I live in New Brunswick and I am less than a one hour drive from Maine and even when I hit up Sunday River / Sugarloaf for a week or two to snowboard and party I encounter americans who cannot for the life of them keep up with Canadians. I personally blame your shitty beer.
