This is the weekend where summer starts acting serious: big outdoor music, real market wandering, zoo mornings, and enough food-truck stops that you can build a plan without overcommitting. I would pick one anchor, then keep a second plan nearby in case the weather gives you a clean evening.
There is a little Stampede warm-up in here, but not so much that it eats the whole issue. The better move is to use the weekend for what it is: a country festival if you want scale, a night market if you want easy, and a few family plans that do not require inventing logistics from scratch.
Start with the top picks, then use the filters if you already know the kind of plan you need.
