That's at one of forest preserves down the hill from me.... It's pretty deserted and a good place to test your launches....
If you look, there were only two or three cars in the parking lot, and they were pretty far from where we were "testing"....
I live in the second house across the street from the forest preserve here... There are 5 different picnic areas within 1 mile of my house.... One of the entrances is across the street from the neighbor across the street from me.... (If you can follow that....) I can be in one of the picnic areas within 5 minutes walking from my front door.... Of course I don't do the burnouts in the one closest to me.... There are many to choose from not far from here....
