In pictures: Your equator memories

From Allen, Baltimore, US:

"A few years ago, my identical twin brother and I visited a monument to the equator near Quito, Ecuador.

As diverse as the world is, and as different as the south is from the north, we decided for one moment to give the world a peculiar symmetry."

Episode Two of Equator is broadcast on Sunday 3 September, 2006, at 8pm on BBC Two.
