Anyway, this was a good time to do this one as there was no one around except for a groundskeeper. I went to the first waypoint only to find lots of beer bottles and matches lying around. After finding the first cache surprisingly quick, I trashed those out. This must happen often because after I came down, I saw the groundskeeper go up to clean.
I found the cache OK, but there was more trash and balloons around it, so I trashed them out too so the they wouldn't attract attention to the cache. There have been lots of caches in this park and for some reason they never seem to last.
