I don't know about you, but when I was a kid, I walked all over the place. The library was a mile away and I regularly walked there carrying many books – even when I was a pretty small kid.
I remember going to the pet store and Pop's, the liquor store with the array of candy. As much as those urban destinations, though, I went with my friends up into the hills – still within a mile or less of home – but scrambling around on rocks & under trees, catching lizards, making up stories.
Or we'd head down to what is now the Martinez marina park, but was then a big tidal flat of trails through the cattails. I'm sure the walk home helped shake enough of the mud I acquired to prolong the life of our otherwise-doomed washing machine.
Pretend you don't have a car available to you and you don't have more than $5 saved up from your allowance. Gotta get home in time for supper, but otherwise you're free.
Go find the world near your home and do some kid stuff.
