I once visited Lindisfarne. I remember joking about all the idiots that disregard the warnings, or cut it too close. On the way back to the mainland we stopped on the causeway to make some sketches from what we figured was a pretty unique perspective. And of course we somehow lost track of time. We made it back just fine, but with a narrow enough margin that we felt rather sheepish.
