Anyone remember the McDonalds commercial in the 70's that stated you can feed a family of four for five dollars and get change back? I bought my kid a meal deal there the other nite. $11.00. Hears your 12 cents change. Hory chit.
Now, as for bike jumping

My older brother set the world record ( we thought) He jumped his one speed wonder over a 74 Honda civic. Landed so hard the frame buckled and both pedals were on the ground at the same time. I tried to duplictae the feat on my ape barred, banana seated, sissy bar 3 speed and ended up with two broken collar bones, sever lacerations to my head and a nasty shiner. All which I wore with pride for weeks

National geographic had "Boobies" in it.
Milk came daily in a truck and you found it in the "milk box" which was a hole in the wall with doors beside your house door.
Taking the bus cost 5 cents. On really rainy days, we would part with a nickel of our snow shovelling or grass mowing money so as to arrive at school semi dry and not have to sit in wet gotch all day.
We each had a list of chores we were expected to do every week or the priveledge of spending the weekend hanging with our friends was revoked until said chores were done.
We could play "army" for hours on end with toy guns, sawed off hockey sticks or whatever you could find.
Street lights meant curfew.
CAR! was the cry of the surburban hoser in training. It meant move the hockey nets and let the cars drive by on the road.
I can't think of the last time I saw a group of kids playing street shinny.
