I have information pertaining to a clean-up day at the park. It will be June 7th. i am guessing fairly early start time.
This is a community wide organized effort that several companies such as mine are involved in along with non profit organizations.
The exact project consists of clean-up of trash and debris that comes from external sources into the stream and lake at Shawnee Mission Park. Project may not last all day; volunteers work as long as they want. Not sure of the exact location of the park getting the attention but i think a show of enthusiastic disc golfers would be awesome.
I was told all volunteers are invited to a community picnic.
Call if you are interested or just show up.
