Another sign of Spring for me, is the change in street cleaning utensils (about which both winter and summer versions I seem to have a strange obsession). As the sun begins to shine, the shovels and scrapers and ice-breaking crowbars are being replaced with little swish brooms and wheelbarrow variants.
We have also had a subbotnik* in the public outside areas at work - which I missed - and meanwhile the Mayor is talking about cleaning up the decaying entrances and yards of Moscow's housing blocks. This would be a massive investment as a huge amount of housing has been left to decay in the post-soviet period (and was not well looked after in soviet times) so I am not sure I believe it. And of course the public zones of stairs and entrances have suffered worse. A public campaigning group called чистый подбездChisty Podyezd/Clean Doorway has been getting people to post pictures to their website of bad examples, and giving prizes to the worse!
* to quote directly from Wikipedia - "Subbotnik and voskresnik (from Russian words суббота [suˈbotə] for Saturday and воскресенье [vəskrʲɪˈsʲenʲjɪ] for Sunday) were days of volunteer work following the Bolshevik seizure of power. The tradition is continued in modern Russia and some other former Soviet Republics. Subbotniks are mostly organized for cleaning the streets of garbage, fixing public amenities, collecting recyclable material, and other community services."
