Reader's Digest cartoon: Train of thought

"Please keep all your belongings with you at all times."

From the August issue of Reader's Digest. I probably had an expression on my face much like the woman's here as I stared out of the train window and came up with this idea. This was also used as one of the Beat the Cartoonist drawings at this year's Shrewsbury festival.
