PSBS Annual Club Picnic 2025
NOTE: New location – Blackwell Forest Preserve in Warrenville
This year’s summer picnic will be held on Sunday, June 29, from 11 to 3, at Blackwell Forest Preserve in Warrenville, IL. It is located NW of the intersection of Winfield Road and Route 56 (Butterfield Road). The entrance is from Butterfield just west of Winfield.
We will be located in the North Pavilion. (see map below)
Our club picnic is the perfect time to come together and enjoy bonsai. We should take this opportunity to bring a tree to show others, and bring trees that you would like advice on. It is a great time to hang out together and work on trees. Nothing beats a summer day talking bonsai and wiring trees.
Lunch will take place around noon. The club will provide burgers, hot dogs, and drinks; members are asked to bring their sides and share.
Members, please plan on bringing a dish to pass and a tree or two to work on. The club will have our wire box available if people need wire for their trees.
So we hope to see you on June 29!
