That's right, the game was called "Land." We played it, along with "Tanks" and some other game... It seems it involved digging and piling up dirt using a small knife))) Hehe.
We also built huts and lit bonfires in the yard... Sometimes we melted lead, which we found in old batteries near the garages... First, we would break them open, pour out the contents, if there was anything inside, we would take out the plates, clean them... We would find tin cans, screw the lid onto a stick so that the can would stay in place... Then we would put the lead plates on the bonfire))) After melting, we would pour the liquid lead into bricks (which have a recess), and wait for it to cool, and then we would take them out)).
Sometimes we played with calcium carbide... it's a white stuff... We would take a bottle, pour water into it, and throw in the calcium carbide... We would shake it, and then everything would swell up and explode... I remember one time when we started kicking the bottle, and one of us threw it onto the road... And just then, a KAMAZ truck was driving by... and it seems it ran over it :\... Then everyone ran away because it stopped... I think... I don't remember))
