Hi Gig Harbor!
What a beautiful place to sail your new TI!
As far as Sailing groups I would check with your Dealer.
Most are starting Island Owners groups/clubs in their general areas.
You could always ask if there are others asking to sail with other Island owners and get their names or maybe you would like to help your dealer start the first "gig harbor" or "puget sound "sailing group!
You can also go on Hobie's NEW Facebook Page and share your pictures and adventures there with other Hobie Island Owners. http://www.facebook.com/hobieislandclub
If you have a dog that likes to go sailing there is also a contest too!
Happy Hobie Sailing!
