This cache is micro, but not nano. It shouldn't be too hard to spot. Initially tried to find a spot in the park where I could hide a small cache and not a micro, but I gave up after 30 minutes of looking. Maybe I'll find a spot some day.
When putting the cache back, make sure it is secure in its spot and not wobbly. Also close the cache itself tightly.
Brookline is a beatiful neighborhood with many fun public parks and places to have picnics, including in this park right here. It was also the childhood home of JFK, whose house isn't too far away. Neighboring brighton also has fun parks and activities to do there.
Congrats to Shadowfax_ for the FTF!
