You know those people who have to park in the back of the parking lot because they think their car is special and cannot afford to have it scratched by someone opening their door? Well, all that does for me is shows me they will have a great reaction to someone messing with them. My friends and I used to go get tons of shopping carts and outline their car with them. We wouldn't scratch up their car or anything, just surround the car with carts. It is best to do after sunset so the Walmart workers don't move them. You also have to be a bit patient because you want to see the person come out of Walmart and you don't really know when that is.
Cheap and fun things to do around Minneapolis/St.Paul
