It seems that there is/was (always) a need for people to meet with other people and exchange ideas, chat, learn new things and maybe collaborate and plan something (possibly) useful. In a natural environment were common activities and living together for some days is a nice experience and not rush in a shopping mall with thousands of people.
Organizing an event requires a lot of organization but it seems that is actually quite doable. Perhaps it’s time to introduce some smaller events in regions where is usually warmer (human-friendly) and (hopefully) don’t require that many resources.
If you have any ideas, directions or want to help with organizing such an event please chime in.
