who don't want shops in their neighborhood. you're going to have drug warriors who are clinging to the past that want to push back on it and will look for any opening to try to roll it back. so it's a good thing that colorado's going this very methodically. i think the comparison to black friday is pretty revealing. david can talk more about that, but it was a very peaceful gathering, despite these long lines and these long hours and the high prices people had to pay. >> david, what would you say to people that would look at marijuana and be concerned about what their kids might think about it or as some people have described it, as a gateway into the possibility of other drugs. obviously, you have a different respect for what marijuana means. what would you say to parents out there that might be concerned about what it really means and tougher conversations that need to be had about recreational marijuana use? >> i would say be honest. be honest with yourself about the fact that marijuana is less harmful than alcohol, a substance that has dangers.
