Yes this is annual at both the capitol and in Boulder. Has happened every year that i can remember.....
The High Times Medical Cannabis Cup is on 4/21, 4/22 this year, although i have heard rumor that it is not going to be the absolute smoke out that it was last year. Still considering going though, but without the medical area and Attack of the Show being there it will not be what it was last year by any means.
The big one i am really looking forward to is the Indoor Grow Expo on 3/11, well its the 10th and 11th but the 10th is much harder to get into, for business owners. If you have been before you know why to go again, if you haven't been all i can say is give it a shot, i have a link to free vip tickets (haven't checked to make sure its still there in a week, but i imagine it is) so all you have to do is pay to park, $10 last year.
Welcome to the community by the way, you will find we are a very welcoming group, well most of the time
