At Our Meeting: Monday, November 12, 2007

Location: Greenbank Mill, Prices Corner, Wilmington, DE

Program: "The Land Beneath Our Feet"
by Tom Pankratz

We started a journey at the edge of our universe and traveled through time and space to present day Delaware.

We stopped here and there along the way to take a look at Delaware as it's geology and biology unfold, stopped for a bit longer to look at our present geology,
and ended up by wandering off to a possible future.

Times: 7:15 - 9:30PM

Refreshments: See Sophie Homesy
