Spent the first four years of my life in a house with a black and white TV with turn dials. We got a color TV when I was 5 (1980). All we had was two channels up until 1992 when we finally got a third channel.
I once decided to run away from home when I was six because I felt mom and dad were mean. My dad helped me pack lunch and a blanket and waved me off at the door. I spent most of the day sitting in a field, eating my sandwiches. Then I went back home. My dad said "Hello, how was your trip?" and that was that.
My playground had an eight meter (roughly 26 feet) tall climbing setup that was built from telephone poles and various configurations of chain covered in the orange plastic. Ropes, nets, you name it.
We once rode pedal cars downhill and I wiped out and ended up in the ER with a bad concussion. When I got back home, we did it again and our parents weren't overly worried.
Doctors would ask my mother if she beat me. She would say: "No, but there isn't a tree in a 10 mile radius that he hasn't climbed and fallen out of."
We built a camp down by the river bed. Once we realized a marauding band of rival boys had been through our turf we built a palisade with sharpened ends and we started guarding it after school. It ended in a battle with bows, slingshots, and spears. Nobody got seriously hurt, we knew better than that. They never tried to mess with our stuff again.
Once me and a friend went missing for a week during summer without much notice. Nobody was overly worried. We had gathered our survival kits, knives, pots and pans, a tent and some other camping gear, "borrowed" a canoe and headed downriver where we found a small island upon which we set camp. Hunted squirrels and used water purifiers to clean the water. We switched to boiling the water since the water purifying tablets made the water taste nasty. When we came back our mothers asked semi-curious where we had been. We said we'd been paddling the river. They shook their heads and went back to cooking dinner.
I had to tape all my favorite songs from the radio.
My dad took me out in the woods when I was 8 and let me fire his AK4 (G3A3) out over the peat bog. He had it set to three round burst and was standing there waiting until I squeezed the trigger believing I would be shooting a single round. I fell on my ass after the third round went almost straight up in the air. My dad laughed until he wheezed, slapping his knees. I put the safety on and stood up, handing the assault rifle back to him.
We didn't have 20 speed bikes. They were one speed, and hard as hell to get up over a steep hill because of this.
I got a portable game (Game & Watch) called Egg some time around 1981. The next year I got the game Oil Panic, which was a dual screen. They were both using fixed position LCD light-ups to display the various modes in the games. These days I play 3D first person shooters on my PSP.
My favorite childhood TV show was a sock puppet.
I can go on and on...
