Where in Denver can elite clones be found without a med card?
The red card is not important, like boston said it's about knowing the right people. If you are in a hurry to get out of state, stick to craigslist. Come on vacation and leave on probation is the new state motto.
If you are looking for a specific strain just call the dispensary, let them know what you want, and they will put a label on whatever they have laying around and double the price.
Also, shops that sell clones do not sell their best stuff, and especially their own crosses and proprietary strains. I could be wrong but I doubt they'd be enabling their customers to put the dispensary out of business or allow other shops access to their 'elite clones'. What's your definition of elite?
westword.com, cannapages, leafly, leaf buyer, and ten other magazines advertise where to get what you are looking for. Or find a hydro shop and don't act like a cop.
Lastly, look around here and use the search function. There are more than a few posts exactly like yours, made by people who didn't search prior to posting.
Good luck.
