Step 2Find a suitable store

Find a suitable store
Look for a store with shopping carts with one funny wheel. It's usually the front left wheel of the cart. There will also be a metal bail on the rear left wheel to prevent the cart from tilting backwards. It doesn't actually work, but that doesn't matter-- it just makes cart locking even more fun. A yellow line painted around the parking lot is usually a good clue as well.

CAPS systems will make a satisfying "thwack" when the boot hits the ground, but on smooth ground, people tend to just keep pushing. There is nothing more you can do after that, because the boot has to be reset manually by an employee with a magic wand. Here are the stores that use the CAPS system.

Look for a GS2 setup for more fun. These systems have a longer range, are more effective at stopping the cart, and can be reset remotely (by you). Build two systems, and you can cause all sorts of trouble.
