Thanks guys.  She did good work.  (www.alexismccarthyart.com)

Anyway, in other news... a challenge for you (no fair for Wes to play)

There are two telephone poles. Each one is 100-feet tall. They are parallel and some distance apart.

Attach a 150-foot rope to the top of each of the poles. This rope will droop down somewhat. That drooping rope is called a catenary, from the Latin word for chain.

What is the distance between the two poles, so that the lowest point of the catenary is 25-feet above the ground?

first correct answer gets a cookie...

If the rope is 150' long and each end is attached to points 100' off the ground, the only way for the middle of the rope to hang to a point 25' feet of the ground is if both ends are hanging from the same point.

So the answer is zero.
