[TIPS] Walk a straight line

Do you recall the mashup I talked about some time ago called,"If I dig a very deep hole, where will I end up?" It's a mashup found here: http://map.talleye.com/bighole.php. Let your students try it. They'll be amazed where they end up - and it's likely NOT to be in China.

Anyway, this one is from the same site: http://map.talleye.com/ But here you choose a location and a direction and it wll plot out your path as if you walked a straight line in that direction. It's not going to be at all what they think for THIS one, either.

Dble click PA on the map, or zoom in and let them start on their house, if you wish. When you dble click that spot a green(ish) flag appears at that spot. Click it and it will let you choose the direction. When you do it will plot it. You can even see it the readl Google Earth, too, if you wish.

Pretty neat.
