I've only smoked weed outside in public in the US once, other than bowl crusing but I consider that different. Anyways it was when I was walking home from campus late one night with a friend. Otherwise in Europe I believe that it's way more accepted to do it in public so I've done it several times there.

Oh shit I just thought of this. I've smoked outside on my front porch tons of times w/ my friends in broad daylight in a college town lol.
