Threat Down: Escher Skiers

If they look this ungainly on cross-country skis, they are likely to be menaces on the roadway. The longer I look at this, the more I can reverse left and right limbs, resulting in multiple possible positions. Quite twisted. Watch out!

This looks like one of those signs that might mean - 'watch out for elderly persons on skis!'

[Patty J]

HAH! This one is crazy - can't look at it too long 'cuz of the Escherness... :)

[Chris Busick]

That's great!
