Chicago Parks - Olympia Park Mystery Cache

Many thanks to Petergalembckes for letting me extend this series.

The Cache:
Contains only a log and pencil. Might want to bring a pen -it writes better.

The Park
This park was a mainstay for my childhood. I played T-Ball, Baseball and Soccer in this park for years. I used to bring my dog here to play on the playground at night (he loved it!!!) Nowadays, you can't really be in this park for longer than 15 minutes without seeing a jogger, dogwalker, or other muggle just walking around.
This park is extremely Dog-friendly. Often at night, many dog walkers will meet in the center of the park to let their dogs run free around the park. The park is open until 11pm last time I checked.

The History
Olympia Park takes its name from Olympia Avenue, the street on its northwestern border, which in turn makes reference to the ancient Greek site of the first Olympics. Local residents established the Edison Park District in 1913 to provide recreational opportunities for the developing community. Twelve years later, the Edison Park District purchased a 10-acre tract of open land to create a much-anticipated athletic field. The local athletic association pushed for rapid improvements, even offering to help with fund-raising efforts. The park district quickly responded by grading the site, laying out a baseball field, and erecting a grandstand.
In 1934, the Great Depression forced consolidation of Chicago's 22 independent park boards into the unified Chicago Park District. By 1940, the Chicago Park District had improved Olympia Park with a children's playground, tennis courts, and an athletic field that was flooded for ice skating in winter. The park also became known for its 14 beautiful flower beds. During the 1950s, the Chicago Park District constructed a small recreation building in the park. This was remodeled and expanded around 1970. In 1980, a meeting room in the Olympia Park fieldhouse was named in honor of local resident Fred Norton, who was instrumental in lobbying for the fieldhouse expansion.

The puzzle-
A play from the Game 1 of the 2006 NLDS.
Less than nine outs into its duration, the lasting image and memory from this National League Division Series between the Dodgers and Mets may have been created.
It was a double play that the Dodgers found hard to recreate, and one that was so improbable that it's difficult to explain.
With nobody out and runners on first and second base, Russell Martin drilled a single toward right field. When it hit off the wall, it seemed definite that Jeff Kent and J.D. Drew would score. Until it happened, never did it seem likely that the play would end with Mets catcher Paul Lo Duca tagging both Kent and Drew out at the plate within a matter of approximately three seconds.
When the ball hit the wall and bounced directly to Mets right fielder Shawn Green, Kent yelled, "Let's go, let's go."
Unfortunately, the much faster Drew was already coming and coming hard. Green made a perfect throw toward second baseman Jose Valentin.
After waving Kent home, third base coach Rich Donnelly turned toward the plate, expecting to see one out recorded. He then saw Drew breeze by and knew that potential disaster loomed.
Knowing there'd likely be a play on him, Drew looked toward right field to see where the ball was. A split second later, he turned back toward the plate and saw Lo Duca tagging Kent.
"I froze in my tracks right there," Drew said. "In hindsight, if I'd have kept running, I'd have probably been safe, because Lo Duca tagged and looked right up at the umpire. I'm just so mind-boggled."
