I wish I could, but I can't, I got a Doctor to blame for that...
What about hiking or biking? There is so much fun outdoor shit to do here in CO. Pick a new hobby or pasttime that involves getting outside and you can meet other likeminded people doing the same thing. Then you can smoke weed outside when you're doing said activity.
Don't scoff at Phish either man, that shit is tiiighhttt. I can have the same amount of fun at a Phish show that I can at a Lamb of God show, albeit different kinds of concert fun
