From the webiste -
Please Note:
The Pacific Rim Bonsai Collection values the safety and comfort of all of its visitors. We respectfully ask that all visitors assist us in maintaining those values by following our guidelines:
While visiting the Collection please refrain from touching the plants or walking in planted areas.
The Collection is a smoke-free environment and we discourage the use of cell phones and electronic games or toys.
There is no picnicking allowed at the Collection. Maps of neighboring parks and restaurants are available in the Rhododendron gift shop.
Pets are not allowed in the Collection. Service dogs are allowed when wearing an identifying blanket.
Personal, non-professional photography is allowed. Each bonsai display is owned by Weyerhaeuser Company and is protected by copyright laws. To photograph the Collection or use images for commercial use, please contact Curator, David De Groot at 253-924-5206.
Anyway, I'll be cautious and try to contact them sometime this weekend.
