Because the moon is small compared to the Earth, the shadow it casts isn't very large. The small size of the shadow and the rotation of the Earth mean that where you need to be to see a solar eclipse is very specific and changes from eclipse to eclipse. To see the next total solar eclipse, you'll have to travel to Northeastern Australia or North New Zealand on November 13, 2012. Good luck!
During a total solar eclipse, the umbra or darkest part of the moon's shadow creates darkness on a small section of the Earth's surface. The penumbra is a part of the moons shadow that is more wide spread and not nearly as dark.
your shadow
an umbra is the center of the solar eclipse which is the darker part and the penumbra is farther away from the center of the eclipse and is brighter than the umbra
True. The umbra is the central darker total shadow of the Moon. Outside of this area, called the penumbra, is the lighter partial shadow. In this area, you would see a partial or annular eclipse. The umbra and penumbra are cone-shaped areas of full and partial shadow. The solar eclipse of January 14, 2010 (last week, as I write this) the Moon was so far away from the Earth that the umbra didn't reach all the way to the Earth. So the Sun was visible all the way around the Sun; and "annular", or ring-shaped eclipse.

These areas are said to be in the umbra. From Britannica Online Encyclopedia (http://www.britannica.com/EBchecked/topic/613811/umbra): "in an eclipse of the Sun, the regions within the umbra experience a total eclipse and those within the penumbra, partial eclipse."
To see a total solar eclipse, yes. However, you need only be in the penumbra to see a partial eclipse.

When it occurs, a solar eclipse is visible over only a portion of the earth. In order to see it, you must stand: -- at a place on earth where the eclipse will be visible, -- outdoors -- in the daytime, i.e. between the hours of sunrise and sunset
umbra is the shadow and penumbra is the part the umbra is in
