Hi Jon, I don't know Lacy very well, except as an exit I drive past going other places.
In Seattle and Tacoma there are lots of car shows and if you go to a few and strike up conversations with the owners of the trucks most like you want yours to be you should quickly learn which shows near you are best and you'll have probably met at least one or two club members along the way.
The Olympia chapter of ATHS is pretty active including doing an annual show out in Shelton. If you are restoration oriented ATHS is a good club to join. The show in Shelton always has a good mix of modified and original trucks.
