I might travel with more than I "need"
And sometimes it is a lot for me to cart around airports.

I'm always on the look out for these carts. They can be up to $4 each time if you pay for them.

BUT

If you have eagle eyes, you can almost always find one on your way down to baggage claim or just outside baggage claim.
Why just stand there and stare at the carousel? Take a few minutes, walk outside and you might find a cart to help you manage your bags.
Or maybe you don't travel with one bag filled with just shoes - maybe that is just my crazy way.
