The Leprechauns: The lamp post and sign where this cache was located are gone now. Just after I maintained the cache in June! Since I now live in Cincinnati, and I only visit Pittsburgh every two months or so for work, it's time to retire this cache after a good run of more than twenty years. Perhaps someone else can find a place to hide a durable cache at this high traffic, oft-changing tourist hot spot location. Thank you to all who visited.
