I grew up in the western suburbs of Minneapolis. There were lots of kids hanging out, as we’d all get kicked out of the house all day. We’d usually play baseball all day in the brief summers, but the rest of the year offered other playtime activities. In the winter could have as many as 30 kids in a giant snowball fight. We’d be running from one block to the other, and build big snowball forts and you’d try to capture from the other gang. There were always these forts in different stagers of repair When we were young teenagers, 13-15, during the warmer weather, we could steal lumber from these new housing construction sites and build tree houses. Sometimes there would be 10 kids involved (there’s nothing you couldn’t do with a critical mass of kids). We would get these big sheets of plywood and cut them around the branches, creating these elaborate multi-storied houses. We wouldn’t have ‘official clubs” and didn’t really hang out as much as just build the things. Still no girls were allowed. The houses would last a couple of years although they might get taken over by gangs from another neighborhood or vandalized by kids who might be mad at you. One time a contractor who got mad at us for stealing the wood sent a bulldozer over. They wrapped a big chain around the house and pulled it right our of the tree. This was the biggest one we had ever created literally 5 stories high, skewed all around the tree to fit in. That house was the culmination of our architectural endeavors. When it was pulled down, we were ready to move on.
