Not really a park and grab at all! Use your head -- be carefull and park on the side street.
Watch out for muggles! This is a busy street and popular cut-through for kids walking to and from school. You might have to wait a bit for the coast to be clear.
No room for swag and bring your own pen. Please re-hide very carefully, and replace as you found it -- which might be a bit tricky but be patient. Please make sure everything is secure.
