Searched for: Lots of Googling on the Young Pioneers and Moscow in the 70s, which led to some pretty useful results but didn't answer everything. Also, I have a friend who was in the organization, but in the Ukraine and a decade later.
Our protagonist joins the Young Pioneers in 1973 at the age of 10, and later is recruited into the Komsomol at 15. My questions are:
1. How regular were meetings? Would they have been very structured, or more of a drop-in type thing?
2. My aforementioned friend has awesome stories about shooting off AK-47s at summer camp. Was this a common experience? If so, how significant a role did military training play?
3. The character has a somewhat famous last name and is from a aristocratic family that fell on hard times before the Revolution. His family since then have been good little Soviet citizens; would he still be under an unusual amount of suspicion or otherwise given a hard time?
