are you an SSA member? *it is available onwww.ssa.org

I am not a member; in fact I'm not much of a "joiner" at all.

Well, if you're not a "joiner," then don't expect free content, like
this and many excellent articles.
And like it or not, you are a "beneficiary." The SSA does loads of
good stuff, like keeping the sky above you open for glider flying,
keeping the FAA from regulating your glider out of existence, and
maintaining a topnotch website full of free material. Maybe it's time
to "join" anyway.
