Good thinking

Two brunettes and a blonde are driving in the desert when, all of a sudden, their car breaks down.

As none of them have any motoring knowledge, they decide to walk. Each of them decides to take one thing with her.

The first brunette takes some food in case she gets hungry, the second brunette takes some water in case she gets thirsty and the blonde takes a car door.

When questioned about her choice, the blonde replies:

"Well, if I get hot, I can roll down the window!"

Tay Railway Bridge

In 1871, the foundation stone was laid for the Tay Railway Bridge to be built across the mile-wide Firth of Tay on the east Scottish coast.

It had a clearance of about 88-ft above the high water mark in the middle of the firth to allow ships to pass up the Tay to Perth.
