Hello russian friends. It is nice to see that you are also playing airsoft (or strikeball as you call it).
End of may / start of june there will be an event in Sweden, Operation Frost: 4. Around 400 people. If anyone is interested please go to http://www.opfrost.org .
Also the main forum for the swedish airsoft-community is http://www.airsoftsverige.com/forum/ .
