Are there corona limitations re groups, social distancing etc in Sweden?
Nothing illegal (yet) but people are adviced to keep a safe distance. I suppose a gathering of 50 people is not the best these days, but being outdoors should lessen the risks.
From what I read recently, and know of Sweden culture, these things are advisory. More of a "here is the information, we will offer help, you can decide for yourself what is best".
Looks like you need to create smaller groups from now on.
Yes to smaller groups. This Tuesday (31st) was supposed to be the last before the (now cancelled) O season but it was also cancelled since it was too popular. Dividing into smaller groups may be a solution but we'll have to wait and see.
