Balloons may be a problem in AK since I dont think theyre allowed. What I do is to take a bright color bandana, iron on contrasting colored letters spelling out our last name. Using lots of safety pins, I pin it to the sunshade. When I park the stroller, I open the shade and its very easy to spot it when looking for it. I also use those stick on labels that you make (or you could use address labels) and put them in a few places (some openly, some hidden) so that if by chance someone did take our stroller, I would be able to id it. Some bright colored duct tape on the frame works too.
