Wagon full of Arrowheads

I encountered a mountain lion and there was a nearby tomato cage. I used the tomato cage to defend myself against the big cat. It was just enough to keep the danger at bay as the lion didn't appear to be that aggressive. I decided to record the episode (to the distaste of my wife who was also there). Later on, I was looking for my littlest sister in a large city. The city turned out to be Des Moines but then, later on still, it turned out to be my mom's backyard. Still looking for my sister, I unloaded a wagon I was pulling behind me. For some reason I was pulling this and it was full of my mementos- I was looking for my cell phone with the recording on it but couldn't find it. After coming up empty, I put everything back only to notice a huge amount of ancient stone arrowheads. I heaped up handfuls upon handfuls back onto the wagon and proceeded onto the other side of the deck.
