As a retired analyst I understand what should and should not be input to
data tables.

However to debate the issue, I would expect that more gardeners know their
plant growing zone far better than they know their lat and long. In
addition some people live in micro climates and even tho' they live in
Zone
6 may be able to grow Zone 7 plants if they have a very sheltered area or
maybe only Zone 5 plants if their gardening area is very exposed to the
elements.

For giggles, I pulled up a hardiness map for MD, my home state.

It appears we have everything from 2a to 11. It seems asking for Location
and Zone will be important.
