  • Peter

    What about Ireland is there any under the radar 😁

  • Jameson Chatman

    Great write up Hannah. Just curious, do you have a list of the best shows to attend for industry professionals? I respect the fun, 420 focused events, but to move forward in our movement we will need to gain much respect on a Federal/National level. This will mean many, many professionally organized events focusing on technology, science and commerce. I’d be interested to learn what Leafly’s favorites are in this respect. Thanks – JC
