Talking about magic fairies
Whether AMS or BCN, it will depend on the team and the means
Last year was an interesting experience, but also personally, an eye opener. I can't thank enough the (Chinese) volunteers that helped make it possible and stepped in to deliver what others had promised.
AMS has simply lost its charm. Yeah sure, you can smoke out and it's a small city (city centre anyways) but you won't find good herb, unless guided by a local. Prices for weed and accommodation are simply ridiculous, and then you still have to eat.
In BCN you need to (ball)sac anything you want to take out of the club, but weather and food is better. You will get a fine if caught by popo, but it should be less troublesome than in AMS with concentrates. Then again, many friends were made and many clubs are keen to welcome us, so that shouldn't be a problem.
Just my observations.
But anyways, let us know, we need to make plans.
