Yep, you ate lunch at any one of the neighbor's houses you were playing around or whoever's mom was making the "best" lunch. Mac & Cheese, Spaghetti 'Os, grilled cheese, pizza, cold cuts sammiches, hot dogs...
Back in that day, most of the wives where stay at home mothers. Houses were rarely locked (at least in my neighborhood).
Had to check in for dinner (supper in the midwest), eat, do dishes.
If allowed to and after dinner then we set off to play kick the can (https://www.youtube.com/watch?v=4TdcrkirZMM).
We also played "Army." All kids bring their plastic play guns and stuff. Split up into teams. One team sits in the garage while the other team hides their guns around the predetermined playing field (from house X to house Y). Then other team repeats the process. Then it's a go. Run and hide. If your enemy shoots you, you play dead for the count of 30. The kid that shot you can steal your gun and hide it. When you wake up from being dead, you run to get a new gun from one of your hiding places.
Winning team is the one that captures all of the other teams guns leaving them defenseless. Rinse, wash, repeat until the street lights came on. That initiated the final check in... can I still play outside? Sometimes yes but don't go too far. Sometimes no. If yes, you couldn't leave the neighborhood out side of shouting distance and had to be back home by the established curfew.
I don't remember wearing a watch. If Mom or Dad called your name from the porch, you had like 5 minutes to stop what you were doing and return back home. If not home in time, your curfew was revoked for a day or two.
