Question:

Can a cracked underground iron water line be patched?

Or can some plumber explain in detail what a plumbing company does to fix an underground cast iron water line? This seems to be some big secret only a very few people know. How hard can it be to fix a cracked or disjoined cast iron water pipe? What is involved besides digging a hole, cutting some pipe, and putting some new pipe in and welding it together?

Answer:

It might be in any drawers or boxes around the area. Somebody might have put it in a box for safekeeping, but forgot to take the batteries out.
The Jeep GC is great in snow - and very expensive to keep in fuel - same as your other two choices. None are going to get 20 mpg. Make sure that you get one with FULL TIME 4WD. Part time 4WD is not suited for use on dry pavement - read the owners manual. As noted, a Subaru would get better fuel economy, and do just as well in the snow. Given that you like Fords, I would suggest that you look at a four cylinder AWD Ford Escape (Mercury Mariner, Mazda Tribute), which will to 20 mpg when driven nicely, and has as much interior room as the '99-'04 GC. Other choices in this class are: Jeep Liberty (V6 get 16-18mpg, CRD get 24-28mpg), Honda CRV, Toyota RAV4, etc. Like all used vehicles, get a CARFAX or similar, get complete maintenance records. The latter is worth a 10% to 20% premium.
That the universe is expanding at an ever-increasing rate. The farther a light source moves away from you the more energy the emitted light loses and hence the wave-length is extended which makes the object appear red-shifted (shifted more towards the red end of the visible spectrum). You can look at it that way or think of space itself as expanding behind the object as it accelerates out from us and the light behind it being stretched. Basically, the light has to traverse a greater distance than what it had when it actually left a point in space and time before we saw it, giving the light the illusion that it is traveling slower and thus passing us at a lower frequency. To visualize this better, think of shooting a ball across a rubber sheet. The ball travels at a constant rate, but as the rubber sheet stretches more and more it gives the illusion that the ball is traveling slower (assume no resistance between the ball and the sheet). This is much like the Doppler effect except unlike sound waves, light waves travel at a constant rate. Remember, the vacuum of space is not entirely devoid, so these photons are effected on their billions of years trek across the cosmos.
