Look at the chart legend under "Airport Traffic Service and Airspace
Information". Just beneath the airspace symbology is the statement, "Class
E Airspace exists at 1200' AGL unless otherwise designated as shown above."

Ohhh! I see, the purple gradients are for Class E with a floor of
700', and that's why they show it separately.This really helps my
understanding.

So does Class E have any special restrictions on unmanned free-
balloons? The FAA guidelines on unmanned free balloons says nothing
about airspace classes, only payload. I just thought it wise to avoid
the Class C airspace in my area all together.
