I saw a stroller today with a lock on it! Smart but it's pretty rare for us that we are far from our stroller. If I'm at the playground, I usually just keep the stroller nearby... if I'm at a restaurant, I try to leave it out front where I can see it from where I'm sitting.

These days, we don't use the stroller nearly as much though, which is nice - one less thing to worry about!

Do you lock up your stroller?
