Citi Bike Prompts New Rental Ideas

Dear Diary:

The recent introduction of CitiBike prompted me to consider what other New York City essentials could be rented on the street for 45 minutes, and then returned when no longer needed. Here is just a partial list:

- Umbrellas, for those sudden downpours, and there are no street vendors in sight.

- Shopping carts, for when you buy more than you intended and are too cheap to pay for delivery.

- Flat-heeled shoes, for when your dogs ache from those stilettos you swore fit so well in the house.

- Stilettos, for when you need to up your game suddenly, and are wearing those old flats that won't do.

- Motorized wheelchairs, for when you turn your ankle on that invisible sidewalk crack and can't make it home, and there are no cabs.
