The tours can happen at the same time.
I think February is great…!
I propose we have a skype call ahead mid December in order to pull together all the potential sites for February (as you said, we need to plan 2 months in advance) and groups around them in a dataset similar to the Case Study Adventure in 2014. Some of us have places we think are potentially interesting.
Also, we have overlapping travel stuff already between those who have so far manifested interest to join the scouting: to give you an idea, in Jan/ February with Alex Levene we want to go to Thessaloniki, then to the Vault Fest London event + I might do a Georgia/ Armenia short tour on a difft account. An ER members shared calendar would come in handy.
Do you know someone in Bulgaria Natalia?
