Swedish Stroller Ramps

Another reason to love Sweden, especially if you have kids: Most of its public stairways are fitted with these clever tracks for baby strollers.

Two skinny tracks offer a distinct advantage over a single wide one: You can walk on the steps between them, which means they can be used on really long stairways without risk of baby and parent accidentally rolling down in one tragic mess. Here's one in a subway station that might be mistaken for a ski-jump ramp:

Basically, you're getting all the benefits of a stairway plus the convenience you've come to expect from a ramp.

They're also a personal-injury lawyer's dream come true, so I doubt we'll see anything like it in the States soon.
