Well tommorow i'm leaving for Europe. Were starting our trip from Norway and driving around most all of mainland Europe, no island visits. Were gonna be visiting Amsterdam, and hopefully ill be able to score some buds even though i'm only 15. People say I look "18" but still, I was wondering how much they card, and how much it would cost to buy 5 grams. I don't plan on smoking any, all I want to do is just buy 5 grams and eat it all, ive never ate that much and it would be really expensive to do on Maui. Do most coffee shops have workers that speak english? Any ones in specific? Does anybody know the best type to eat over their, I know they have alot of selection? If I could get answers to these questions before I leave tommorow, that would be sweet. Thanks, ninja-
