Now I understand that the legal age for drinking in California is 21. This presents a problem for my friend and I who are coming from Calgary, Alberta, Canada where we've been able to drink for the past 2 years. We're both 20, but we're wondering just how insistent they are about ID'ing people inside the grounds? We want to be able to drink, infact we need to be able to drink. So how does someone underage get a drink? Is it just a matter of making friends with someone whose 21 and getting them to buy you booze?
