I have a friend who had her stroller stolen at Disneyland and I remember how mad she was. Not only did she have to go the rest of the without a stroller for her 2 year old but she also had to fork over the money to buy a new stroller when she got home. A stolen stroller has always been a worry of mine when leaving my stroller unattended at busy places. After mom Annette Mendoza had 2 strollers stolen she came up with a retractable lock so that would never happen to her again. There was born BuggyGuard.
