A open park with a playground, basketball and tennis courts, and even a spot for skateboards.
Frequently busy place throughout the week.
Find a good spot to take a seat and blend in, see what's everyone up to before you go for the cache.
You also might want to use gloves, just to keep your hands clean from the rust.
The park is assured to be open from 8am to 6pm, so set your plans within this time period.
