I'll third this and add that the Maclaren snap-n-go thing (http://www.maclarenbaby.com/us/index.php?option=com_content&task=view&id=98&Itemid=490) is much better than the other one (Graco I think) we tried. It's more expensive but very cheap compared to a full-on stroller. Also, we park our fancy schmancy stroller, folded up, outside Soundbites all the time without locking and have never had a problem. We don't usually use it right around the Square. It may help that no one can figure out how to unfold it and unlock the wheels in the time required for a quick getaway.
