The cache is located in the Evergreen Open Space, which is a public open space that is always open. It can get pretty busy on the weekends so I would suggest going in the middle of the day on a week day, when there is almost no one there. There can also be a lot of frisbee golf players here, so watch out for flying frisbees! No one really uses the tennis court located close to this cache, so you won't have to worry about any tennis player muggles spotting you, but still keep an eye out for any passing muggles! It shouldn't be too much of a problem because the location of the cache is fairly secluded from view.
This is a really nice space to have in the neighborhood, and there is a path that can take you through the whole park if you want to take a walk. I know there are some other geocaches in here too.
When you find the cache, please do not add or remove anything, except trackable items. I want to make sure other cachers get a similar experience with the dress-up items! Despite lack of swag/trading opportunities with this cache, it is very family and kid friendly and should be a very interactive cache.
