Hi Hamhanded, I can give more information if you will send an email to orca@wavecable.com.
We fly most days weather permitting. Generally it's in the mornings and most of all day on Saturdays.
Memebership is always open. To join, you must be a member of AMA. The cost for ORCA is a one-time initiation fee of $25. Dues are $50 per year, prorated quarterly.
We have had some problems with this web site so not too much activity.
Rick Magnuson
ORCA Secretary/Treasurer
