Marc,

How many CDs choose cyclinders? Of theses cyclinders, how many
are centered at the airport, and how many are remote (centered away
from) the airport?

If remote, are they 2-5km out at 1000ft minimum? What is the
cylinder radius? Is it 1/2km like the previous poster's
"control point"?

For us non-contest guys, this is quite interesting...

The current SSA regional/national rules leave the contest director with
the option of using either a finish cylinder with a specified minimum
finish height (usually 500 to 1000 ft), or a finish gate with a 50 ft
minimum height. When using a finish gate, it needs to be adjacent to the
runway, or the worm burners won't be able to make it home...
