The LVZC in Belgium (organization of all gliding clubs in Belgium) wrote a letter to all clubs to stop all activities for at least a month. The season is starting in 2 weeks, going to be very busy with check rides when we can finally operate again.

at least! - there is little logic in closing for a month. If a cessation of a group activity is deemed necessary then it will have to be for several months. There is no way this is going to be disappearing in a month in any European country.
